CalculateBalance: Calculate balance of covariates before and after matching.

In gpapadog/DAPSm: Distance Adjusted Propensity Score Matching

Description

Function that calculates the standardized difference of means.

Usage

CalculateBalance(dtaBef, dtaAfter = NULL, cols, trt,
  diff_means = FALSE)

Arguments

dtaBef	Data frame including the data before matching.
dtaAfter	Data frame including only the matched pairs data. Can be set to NULL if we want to calculate the standardized difference of means for only one dataset.
cols	Column indeces of the variables we want to check. Should be the same in both dtaBef and dtaAfter
trt	Column index for treatment variable.
diff_means	Logical. Set equal to TRUE to return the difference in means of treated versus controls. Defaults to FALSE.

Value

A 2 by length(cols) matrix with the standardized difference of means before and after matching. (Second row is empty if dtaAfter is not given.)
