regression - Forecasting model for longitudinal data with multiple explanatory variables -
i new stats, forgive me if didn't phrase question right.
subject 1: y ~ x1 x2 x3 x4 x5 @ t=1 subject 1: y ~ x1 x2 x3 x4 x5 @ t=2 subject 1: y ~ x1 x2 x3 x4 x5 @ t=3 subject 1: y ~ x1 x2 x3 x4 x5 @ t=4 subject 2: y ~ x1 x2 x3 x4 x5 @ t=1 subject 2: y ~ x1 x2 x3 x4 x5 @ t=2 subject 2: y ~ x1 x2 x3 x4 x5 @ t=3 subject 2: y ~ x1 x2 x3 x4 x5 @ t=4
i have longitudinal data set (repeated measures each subject taken 4 time periods) dichotomous response variable. wish build predictive model helps predict y @ t=5.
basically, need regression+time series forecasting model tells me variables significant in explaining variability in response, while accounting within subject correlation/dependence structure on time, , forecasts y or probability of y taking on 1 of 2 binary outcomes, @ time t=5, regressing on predictors until t=4.
i have feeler has mixed models/transition models. but, not sure how structure problem in tool r/sas , package/procedure use.
i believe requires incorporation of markov state transition models, accounting other explanatory variables.
any appreciated.
