News of Members
Colorado State University 1. Eileen and Tom Boardman are the web editors for the Quality & Productivity Section of ASA. In this capacity they determine what will appear on the Q&P homepage by working with the section officers (Eileen is a Council of Sections Representative) and the webmaster, Ramon Leon of the University of Tenn. Why not visit the ASA Homepage (http://www.amstat.org) to see what the association's homepage is like. Then select the Q&P section under Section Information. If you have comments on what is or is not there, let us know at "boardman@lamar.colostate.edu" You can also leave mail for most of the section officers too. The Colorado Wyoming Chapter is already on the ASA homepage and can be accessed directly, too (http://www.stat.colostate.edu/ASA). Jim zumBrunnen at CSU has done a great job with it. 2. Tom Boardman attended a "Symposium on Clinical Trial Design and Analysis in Periodontics" sponsored by NIH, ADA, AAP, NIDR, and FDA in Bethesda recently. He reports that this was one of the best conferences he has attended. The speakers were not only prepared with great slides, moreover the program committee had, over three years, agreed on a "common" format. Thus, each talk actually built on previous talks. Research into various area of periodontics will likely be one of the fastest growing areas in the near future. In addition the Nather Conference Center at NIH is a wonderful place to hold a symposium.

WEST, Inc., Cheyenne Western EcoSystems Technology, Inc. recently hired two additional statisticians: Trent McDonald and John Kern. Trent and his wife Mary with two children are establishing their home in Cheyenne while John, his wife Jeanine, and two children will continue to live in Laramie. Trent McDonald was raised in Laramie, Wyoming, and received a B.S. degree in Statistics and Computer Science from the University of Wyoming in 1988, a M.S. degree in Experimental Statistics from New Mexico State University in 1990, and is currently completing a Ph.D. degree in Statistics from Oregon State University in 1996. Trent brings over six years of experience in scientific natural resource studies to WEST, Inc. and is currently involved in research into the effects of heavy metals on wildlife in northern Idaho. John Kern was raised in Michigan and received a B.S. in Mathematics from Lake Superior State University in 1983, an M.S. degree in Applied Mathematics at Montana State University in 1986, and a Ph.D. in statistics from the University of Wyoming in 1995. John Kern has over 3 years of experience in consulting in natural resources and is currently involved in studies of ground water problems associated with the development of coal bed methane in the Powder River Basin of Wyoming. Wallace Erickson participated in a line transect aerial survey for moose on the Innoko Wildlife Refuge in West Central Alaska during March and Lyman McDonald was on a ship in Prince William Sound participating in a survey of harlequin ducks during February. Everyone in the office believes that they were on wilderness vacations, but they swear it was all work. Recent publications: Erickson, W.P. and L. L. McDonald. 1995.

National Wildlife Research Center The last news report from the Denver Wildlife Research Center was in May 1995. Many events, changes (see name above) and activities have occurred since then for the Center and its statistical staff. DWRC's move to the Foothills Campus of CSU is progressing. A state-of-the-art animal research building was completed and is now in use. Plans have been developed for building an adjacent office and lab building, outdoor pens and other supporting buildings. Ground breaking for some of these may occur as early as this spring. In additional temporary office and lab space was located and remodeled to our needs. About one third of DWRC's Denver staff has been relocated to Fort Collins with the rest to follow as feasible. The Center in Fort Collins is called the National Wildlife Research Center and that is how our activities will be referenced in this Newsletter. Bill Dusenberry is responsible for overseeing the planning, construction, and negotiations for these very complex facilities, including the temporary space. Rick Engeman now has an office in both Denver and Fort Collins. Rick is NWRC's only practicing statistician now, as Bill is using his statistical design training to produce a new research center and Heather Krupa resigned last summer to attend to motherhood. Again in 1995, Rick Engeman managed to get around for work. Most travel was due to a long-term project that Rick began on Guam to evaluate the efficacy of operational control and containment methods for preventing the spread of brown tree snakes from Guam. The brown tree snake is a mildly venomous species, exotic to Guam, that was accidently introduced around World War II. It has since wiped out the native birds and causes significant problems with power lines and agriculture. Because Guam is a focal point for military and commercial cargo shipments in the Pacific, there are substantial concerns that this species could spread to other places, especially Hawaii, and cause similar problems. Rick made trips in March and July of 1995 and February of 1996 to work on this project. Additional future trips are also planned. Rick's only other business trip was to Tasmania May of 1995 to present an invited paper on nonlethal animal damage control methods at the Australian Vertebrate Pest Control Conference in Hobart. While there, he spent a week consulting with state and federal agencies, university, and private companies and organizations on forest animal damage problems research. Publications since the last report: L. Allen and R.M. Engeman. 1995. Assessing the impact of dingo predation on wildlife populations. 10th Australian Vertebrate Pest Control Conference. (M. Statham, ed.) 10:72-79. R.M. Engeman, D.L. Campbell, D. Nolte and G. Witmer. 1995. Some recent research results on non-lethal means for reducing animal damage to reforestation projects in the western United States. Invited paper, 10th Australian Vertebrate Pest Control Conference. (M. Statham, ed.) 10:150-154. R.M. Engeman, V. Barnes, R.M. Anthony and H.W. Krupa. 1995. Vegetative management for reducing damage to ponderosa pine seedlings from Mazama pocket gophers. Crop Protection. 14:505-508. M.E. Tobin, R.M. Engeman and R.T. Sugihara. 1995. Effects of mongoose on rat capture success. Journal of Chemical Ecology. 21:635-639.
General A number of chapter members (Barb Brown, Rick Katz, Dick Jones, Mark Berliner, Luning Li, Tim Hoar plus maybe some others) attended the 13th Conference on Probability and Statistics in the Atmospheric Sciences, sponsored by the American Meteorological Society, which took place in February in San Francisco. Some presented papers. Barb Brown can provide information about this conference to anyone interested.
Editor's Note As you can see, several members provided significant news items for this issue. I would like to carry as much news of the activities of chapter members as possible. Anything from little "newsy bits" up to items of major importance to the statistical community are always welcome. Although the preferred input format would be ASCII text via e-mail to my internet address or MicroSoft Word or WordPerfect for Windows on disk, I am happy to accept input in any form that doesn't rely totally on my imperfect memory (such as verbal transmission) at any time before a newsletter publication. I will endeavor to notify members via e-mail prior to planned publication dates but only about thirty percent of the members currently have e-mail addresses on file with the chapter secretary. Please help us complete our listings by sending a note to Barb Brown at bgb@rap.ucar.edu, cc: TomGofBoulder@msn.com.
Chapter Dues Colorado-Wyoming Chapter annual dues are $5.00 per year for regular members and $2.00 per year for student members. You may pay chapter dues through ASA Headquarters along with your society dues, OR you may pay them directly to the chapter treasurer. Note: National membership is not a prerequisite for membership and participation in chapter activities.
Chapter Officer Elections 1996-1997 One standard item of business at the dinner following the Spring Meeting, is the nomination of members to serve as Chapter Officers for the forthcoming year. If there are no more than one nominee for each vacant office, the election is traditionally held that evening and the nominee is elected by acclamation. If there are two or more nominees, ballots will be mailed to all members and the new officers will assume their duties about the end of May. This year Ken Gerow ascends to the Chapter Presidency and we are scheduled select a President-Elect, a Secretary, and a Treasurer. Also, a new Newsletter Editor was supposed to be selected last year but there were no volunteers at that time and I continued on by default. Therefore, we face the potential election of four of the five chapter officers. Barb Brown has served long and faithfully as Secretary and has asked that someone step forward to take up the job. Likewise, Anna Baron stepped in on short notice as Treasurer when the former Treasurer had to leave the area. She has carried out her unsought duties with good cheer and full responsibility but also would like to relinquish them to someone else. Please consider volunteering for one of the four offices or nominating one who would be willing to serve. The ASA Colorado-Wyoming Chapter Annual Spring Meeting Preliminary Schedule: 8:30 Registrant check-in. Coffee and pastries. 9:00-4:00 Keynote address, student papers, lunch break, presentations. (Exact order not yet determined.) 5:30-9:00 Social hour and dinner. (Details follow) Dinner: The Boulder Cork, 3295 30th St, Boulder CO. Happy hour begins at 5:30 with a cash bar, followed by dinner at 6:30 and a short business meeting after dinner. The Boulder Cork provides excellent food and service and you will be able to order from a selection of entrees including prime rib, teriyaki chicken, fresh 'catch of the day' in parchment, or broiled salmon. The meal also includes salad, soup, and rolls. (Detailed directions available at the meeting.) Pre-Registration: Mail-in form on bottom of page 7. Regression Graphics A talk by Dennis Cook, Ph.D., University of Minnesota Abstract: Graphs and graphical methods have always played a useful role in statistical analyses. Recent ad-vances in graphical software now allow easy access to modern graphical displays like 3D plots and scatterplot matrices, and promise to expand the role of statistical graphics. Such displays have found many useful ad hoc applications and allow the user to gain insights about the data during the explora-tory stage of an analysis. Yet a notable gap seems to remain between graphical exploration on the one hand and more traditional model-based analyses on the other, particularly when investigating how the conditional distribution of a response variable depends on the values of one or more predictors. Working in a general regression context, I describe ideas that provide a connection between graphical and model-based analyses. These ideas will be used to suggest graphical methods on modern interactive displays for inferring about characteristics of the regression, with the goal of finding a useful starting point for a traditional model-based analysis. Computer generated displays will be used throughout the presentation to illustrate ideas and methods.
