# Structural Equation Model Sample Size Calculator

Compute the minimum sample size for a structural equation model (SEM) study involving latent variables, given the expected effect size, the desired p-value, the desired statistical power level, and the number of observed and latent variables. The calculator will compute the minimum sample size required in light of the structural complexity of the model, as well as the minimum sample size required to detect the specified effect. Knowing the proper sample size is critical in analytics studies that rely on structural equation modeling (SEM).
