Log Ratio of Standard Deviations
Description
Computes a measure of the difference in the dispersion of the covariate distributions across treatment arms.
Usage
log_ratio_sd(X, D)
Arguments
X |
Covariate matrix (no intercept). |
D |
Treatment assignment vector. |
Details
Log ratio of standard deviations are computed as the logarithm of the ratio of the within-arm standard deviations.
Value
1xp data frame storing logarithm of the ratio of standard deviations of each covariate.
