To fit this model we use therapist/subjects, which specifies nesting. This formula expands to a main effect of therapist and a interaction between therapist and subjects (which is the subject level effect). # lme. lmer(y ~ time * tx +.

In theory, an imputation model estimates the joint distribution of all the variables it contains. MICE breaks this problem into a series of estimations that regress one variable on all the other variables in the model.

Four statistical models are generally available for the **analysis** of **longitudinal** **data**: univariate repeated measures ANOVA model, 1 multivariate ANOVA (MANOVA) model, 2 mixed effects model, 3, 4 and generalized linear models. 5 Generalized linear model is quite distinctive from the first three models as it does not require the normality of **data** and provides robust results against the deviation. bysort stockid: egen maxreturn = max (return) This creates a new variable maxreturn that holds the highest value of return across all observations of each stockid. For each stockid, find the year/s that yielded the highest return. list stockid year if return == maxreturn. Count the number of observations for each stockid. RABE‐HESKETH , S. and SKRONDAL , A.
