  1. *The outcome being modeled in equation (2) is a i from equation (1). AConstrained to equal β AA . BConstrained to equal 0. C Constrained to equal 1/2 β AA . D Parameter value is fixed. Ep-value based on a likelihood ratio test with the general model as the base model.FAIC = -2(log-likelihood) + 2(number of free parameters).
