• James T. Austin, Robert A. Yaffee, and Dennis Hinkle. (1992).Logistic Regression in
  Higher Education Research. Higher Education, Handbook of Theory and Research, Agathon Press, 8, 379-410. This chapter contains an explanation of the statistical theory of logistic regression along with examples of SPSS, SAS, BMDP, and SYSTAT programs of logistic regression analysis. Included is a comparison of this technique with those of discriminant analysis and probit analysis. This is a good basic exposition for those just beginning to learn about logistic regression.
• Robert Yaffee, Valerie Lorenz, and Robert Politzer (1993). Models Explaining the Severity
  of the Gambling Problem among Pathological Gamblers undergoing Treatment in Maryland: 1983-89 William R. Eadington and Judy A. Cornelius, eds. Gambling Behavior and Problem Gambling, (Reno, Nev: Institute for the Study of Gambling and Commercial Gaming), 657-676. This article presents the theory of both ordinal and binary logistic regression analysis. Using real data from the State of Maryland, it formulates a new measure of gambling addiction severity and provides models using versions of this measure to explain gambling intensity on the part of pathological gamblers in that State between 1983 and 1989. The book can be obtained from the University of Nevada Press at Reno.
• Valerie C. Lorenz, Robert M. Politzer, and Robert A. Yaffee (1990). Final Report of the Maryland Task Force on Gambling Addiction. This is the final report of the State Task Force under the aegis of the Alcohol and Drug Administration of the State Department of Health and Mental Hygiene to study the problem of gambling addiction in Maryland. Drs. Valerie C. Lorenz and Robert M. Politzer served as co-chairs of the Task Force whereas Dr. Robert A. Yaffee served as the statistical consultant to the Task Force. From a sample consisting of about 80% of the members of Maryland Gamblers Anonymous Chapters and all of the patients undergoing clinical treatment between 1983 and 1989 in the state, the authors analyzed the prevalence of the illness, the profile of the pathological gamblers, the social and economic cost of compulsive gambling, as well as developed models explaining gambling addiction intensity on the part of the patients as well as those in self-help treatment.
• Robert A. Yaffee (1990). A Profile of Pathological Gamblers undergoing Treatment in Maryland. Appendix E of the Final Report of the Maryland Task Force on Gambling Addiction. This analysis is based on all patients under treatment in all three clinical programs treating pathological gamblers from 1983 through 1989 in Maryland. The Profile includes aspects of family background, histories of abuse, current gambling practices, and psycho-social consequences of the addiction. Ordinal logit and binary logistic regression models are explained and used to develop a gambling severity ratio and from that models explaining gambling addiction intensity.
• Robert A. Yaffee (1990). Severity of Compulsive Gambling and Co-Addiction in Maryland. Appendix F of the Final Report of the Maryland Task Force on Gambling Addiction. On the basis of a sample comprising about 80% of the Gamblers Anonymous Chapter members in Maryland, this analysis analyzes the indications of co-addition to distinguish between simultaneous and sequential co-addiction. The author also found an association between gambling addiction severity, on the one hand, and the commission of crimes and a preference for casino gambling, on the other. It also finds, contrary to intuition, that gambling intensity is inversely related to propensity to drug abuse for patients and inversely related to alcohol abuse for self-help group members. These findings argue for a revision of what is meant by the addictive personality.
• Robert A. Yaffee and Robert M. Politzer (1990). A Review of Prevalence Estimates. This analysis criticizes existing prevalence estimates of pathological and problem gambling in Maryland. It shows how the estimates of prevalence rates were inflated by using older Census population estimates of the counties of Maryland. It updates those estimates and refines the sampling weights and renders a more accurate estimate of the prevalence of pathological gambling in Maryland. The Task Force finds that there are approximately 50,000 pathological gamblers and about 80,000 problem gamblers in Maryland in 1988.
• Stefanie R. Auer, Steven G. Sclan, Robert A. Yaffee, and Barry Reisberg.(1994). The Neglected Half of Alzheimer Disease:
  Cognitive and Functional Concomitants of Severe Dementia by Journal of the American Geriatric Society, 42, December 1994, 1266-1272. This article contains examples of nonparametric statistics applied to the validation of a scale to measure advanced stages of Alzheimer Disease. The article can be found in the December 1994 issue of the Journal of the American Geriatric Society. The programs and graphs were the results of statistical analysis with SAS/PC.
• Robert A. Yaffee (1997). "A Methodological Critique of Kearney et al.'s (1996) Casino Gambling in Private School and Adjudicated Youngsters," Journal of Gambling Studies, 13(1), Spring, 1997, 85-90. This commentary is a methodological and statistical critique of flaws that afflict small sample size research done with bivariate statistics on rare populations. Their impairment of statistical conclusion validity is explained in this article.
• Robert A. Yaffee and Veronica J. Brodsky (1997). Recommendations for Research and
  Public Policy in Gambling Studies. Journal of Gambling Studies. 13(4) Winter, 1997, 309-316. This response to Father McGowan's call for a mature agenda for research suggests that the Gambling industry be held accountable for the pathological gamblers they are addicting, proposes a method for holding them accountable, and proposes a new approach to developing an optimal therapy for treating such addicts. In this article, we advocate policy reform that entails periodic prevalence studies in each state, and a surtax, over and above all existing taxes, to be levied on the gambling industry in accordance with the latest surveyed state prevalence rate of pathological gambling. The proceeds from the surtax are to be devoted to the research and treatment of the problem and pathological gamblers.
