RANDTREAT: Stata module to randomly assign treatments uneven treatments and deal with misfits


  • Alvaro Carril

    () (University of Chile)


The randtreat command performs random treatment assignment. It can handle an arbitrary number of treatments and uneven treatment fractions, which are common in real-world randomized control trials. Stratified randomization can be achieved by optionally specifying a variable list that defines multiple strata. It also provides several methods to deal with 'misfits', a practical issue that arises in treatment assignment whenever observations can't be neatly distributed among treatments. The command performs all tasks in a way that marks misfit observations and provides several methods to deal with those misfits.
