Checking if two categorical variables are independent can be done with Chi-Squared test of independence. I think what you want to do is to study the link between them. when a population is non-normally distributed, the distribution of the sample This means that given knowledge of the probability vector for the categorical random variable, and the standard deviation of $X$, you can derive the vector from any $m-1$ of its elements.).

However, covariates can also be lagged effects if the hypothesized effect is thought to take more time to unfold (e.g., binge eating avoidance yesterday predicts Adherence today) or to delineate between the cause and effect more clearly if one variable was not necessarily collected first within time t. In such case, autoregression in the covariate may be added to the model. @Macro, you are right - another solid argument for having a good definition! It only takes a minute to sign up.
