The plots used by Viale et al 2 are one way of exploring prognostic effects of continuous variables nonparametrically, but a more relevant question is that of an interaction between treatment and a ...

In addition to finding optimal block designs, you can use the BLOCKS statement to find designs that are optimal with respect to more general covariate models. You can specify the data set containing ...

One way of viewing covariates is as extra sources of variation in the dependent variable that may mask the variation due to primary factors. This example demonstrates the use of the COVAR= option in ...

Success is hard to come by in drug development. “On average, 50% of phase III trials with novel therapeutics fail,” says Subha Madhavan, vice president and head of AI/ML at Pfizer. “A primary reason ...
