Note. = N = 377. All models control for sex and family history, with the exception of the sex and the family history analyses. Chrn = chronic; dev = developmentally limited; Late = later onset; non = nondrinking or nondiagnosing; AUD = DSM-III alcohol use disorder.

^aOwing to an inestimable model that was due to low numbers of drinkers in the female family history negative group, these analyses were conducted as logistic regressions outside of the mixture modeling framework.

^bOwing to an inestimable model because of the low numbers of drinkers in the family history negative group, these analyses were conducted as logistic regressions outside of the mixture modeling framework, by assigning each participant to his or her most likely class and running a series of logistic regressions.

^cAs model could not be estimated with family history of alcoholism, parameters are from a model without this term.

^dParameter was inestimable because 100% of the later onset group had a history of depression.

^eOwing to large odds ratios in excess of 1,600, analyses were conducted as logistic regressions outside of the mixture modeling framework, by assigning each participant to his or her most likely class and running a series of logistic regressions.
