Multinomial logistic regression model predicting response class, where the constant respondent class is the reference category.

Note: *p <. 05. ** p <.01. N(Constant respondents) = 2888. N(Explicit Withdrawals) = 447. N(Lost participants) = 884. N(Intermittent respondents) = 1595. Model estimated using Maximum Likelihood with robust estimation of standard errors. AIC = 12748.15. BIC = 13368.27. loglikelihood = -6281.07.
