The MSToolkit R package has been written to help users simulate clinical trials, evaluate designs, analysis methodology and quantify operating characteristics through the application of dose and study level decision criteria. 

• Can simulate parallel group, crossover and longitudinal designs
• Flexibility in defining data generation processes using parametric models
• Data generation model parameters can vary across simulation replicates; parameters can vary between subjects
• The data generation function specifies the linear predictor for the mean response given inputs (dose, time, covariates); inverse link functions allow generation of continuous, binary and count data. User-written inverse link functions allow data generation from a variety of other distributions.
• Model parameters and covariates for each subject / replicate can be generated from multivariate normal distributions or sampled from external data files e.g. existing data files.

This wiki guides users through the use of the package. Help files for individual functions are provided with the package.

An MSToolkit development page is maintained at RForge. The developers can be reached at mstoolkit@googlemail.com
