Balance diagnostics telescope matching

Source: R/telescope_match.R
balance_table.Rd

Provides matching balance diagnostics for telescope matching CDE estimators

Usage

balance_table(object, vars, data, comparison = NULL)

Arguments

object

output from an estimated cde_telescope_match estimator

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 estimate on the cde_telescope_match object.

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).

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.
