    A graph of confidence intervals can be used to report results from a regression model with explanatory variables as factors. In this paper we describe a method for computing and displaying confidence intervals using weighted sum contrasts to compare population means in unbalanced designs. We extend this method to models with covariates and logistic regression models.
