mvregmed.dat.check {regmed}

Helper function to check x, y, mediator for input to mvregmed functions

Description

Assure that x, y, mediator are matrices, check column names and fill in if NULL, and reduce x, y, mediator so no missing values among all three matrices.

Usage

mvregmed.dat.check(x, y, mediator, max.cor=0.99)

Arguments

x

matrix with columns representing "exposure" variable (sometimes called instrumental variable)

y

matrix with columns representing outcome variables

mediator

max.cor
