## S3 method for class 'mimids'
summary(object, n = 1, interactions = FALSE,
  addlvariables = NULL, standardize = FALSE, covariates = FALSE, ...)

Arguments

object

This argument specifies an object of the mimids class.

n

This argument specifies the matched imputed dataset number, intended to summarize its matching profile. The input must be a positive integer. The default is 1.

interactions

This argument specifies whether to show the balance of all squares and interactions of the covariates used in the matching procedure (for nearest neighbor matching method). The input must be a logical value. The default is FALSE

addlvariables

This argument specifies whether to provide balance measures on additional variables not included in the original matching procedure (for nearest neighbor matching method). The input should be a list. The default is NULL

standardize

This argument specifies whether to print out standardized versions of the balance measures, where the mean difference is standardized (divided) by the standard deviation in the original treated group (for nearest neighbor matching method). The input must be a logical value. The default is FALSE.

covariates

This argument specifies whether to include the covariates while reporting the matched sample sizes (for exact mathcing method). The input must be a logical value. The default is FALSE.

...

Additional arguments to be passed to the summary.mimids() function.

Details

The matching profile of the mimids class objects is summarized.
