SMD Balance Calculator

Calculate Standardized Mean Differences for covariate balance

Based on cobalt R package

Covariate Data

Enter mean and SD for treated (1) and control (0) groups

Balance Threshold (|SMD|)

Enter data and calculate to see balance

SMD Thresholds

|SMD| < 0.1: Excellent balance

|SMD| < 0.25: Acceptable balance

|SMD| > 0.25: Substantial imbalance
