what is the interaction term to a gene to predict cad which std is a covariate are alleles an established predictor of cad what type of correlation would cause a covariate to be no longer significant after inclusion of interaction term. is the covariate a gene which variable is an established model and is also an established predictor of cad? is gene an established predictor of cad is an interaction term a covariant which is an established predictor of cad? if the covariate is not significant, the model is still fine. what is the difference between cad and gene how to calculate std what is the difference between the interaction term and the gene in predicting an outcome which gene is used for cad analysis if a gene has a significant effect on a condition that is also an established predictor of cad is the interaction term of the gene an established predictor of cad when are covariates no longer significant which is no longer significant if an interaction term is included? why is the interaction term no longer valid with a cad which covariate is no longer significant after the inclusion of an interaction term?
