This function extracts the results related with estimating results of the interaction test from a "qualint" object. It returns a matrix which contains the estimating results of the treatment effects which will used directly in the testing process later. FOr continuous responses, it is the mean difference. For binary responses, it is the risk difference, log relative risk or log odds ratio. For survival responses, it it the log hazard ratio.
A numeric matrix (see above). For type = "continuous"
,
it is the estimation results for mean difference. For type = "binary"
,
it is for risk difference, log relative risk or log odds ration. For
type = "survival"
, it is for log hazard ratio.
