Balance diagnostics for Telescope Match objects

Description

Balance diagnostics for Telescope Match objects

Usage

balance.tmatch(object, vars, data, comparison = NULL)

Arguments

object

an object of class tmatch – results from a call to telescope_match

vars

a formula object containing either the treatment or the mediator as the dependent variable (which denotes whether first-stage or second-stage balance diagnostics are returned) and the covariates for which balance diagnostics are requested as the independent variables. Each covariate or function of covariates (e.g. higher-order polynomials or interactions) should be separated by a +.

data

the data frame used in the call to telescope_match

comparison

a binary indicator for if the function should return the balance for the treated group ('1'), for the control group ('0'), or for overall combined balanced ('NULL', the default).

Details

Provides matching balance diagnostics for tmatch objects returned by telescope_match

Value

Returns a data frame with the following columns.

  • variable: Name of covariate

  • before_0: Pre-matching average of the covariate in the mediator == 0 (if first stage balance) or treatment == 0 (if second stage balance) condition

  • before_1: Pre-matching average of the covariate in the mediator == 1 (if first stage balance) or treatment == 1 (if second stage balance) condition

  • after_0: Post-matching average of the covariate in the mediator == 0 (if first stage balance) or treatment == 0 (if second stage balance) condition

  • after_1: Post-matching average of the covariate in the mediator == 1 (if first stage balance) or treatment == 1 (if second stage balance) condition

  • before_sd: standard deviation of the outcome (pre-Matching)

  • before_diff: Pre-matching covariate difference between mediator arms (if first stage balance) or treatment arms (if second stage balance).

  • before_std_diff: Pre-matching standardized covariate difference between mediator arms (if first stage balance) or treatment arms (if second stage balance), Equal to Before_Diff/SD.

  • after_diff: Post–matching covariate difference between mediator arms (if first stage balance) or treatment arms (if second stage balance).

  • after_std_diff: Post-matching standardized covariate difference between mediator arms (if first stage balance) or treatment arms (if second stage balance), Equal to Before_Diff/SD.
