But, I'm not sure if there is a different power analysis I should be doing to estimate sample size since I am testing for mediation. There are multiple predictor variables: Multiple regression analysis can be used to examine the relationship between one dependent variable and multiple. See the image below.Įdit: Question 1: Is it even appropriate to use G*Power to estimate sample size in this context? I know you can use it for simple linear regression and multiple regression. for-gpower-power-calculation Multiple logistic regression power analysis. predictors nearly always correlate to some degree in multiple regression models. I am going to run a simple mediation model. Many scientists recommend using post hoc power as a follow-up analysis. Many tools exist for power analyses focused on R2 Model (the variance. If I were to run a simple linear model, say the figure below, I would enter "1" in the box "Number of predictors" in G*Power. GPower is a tool to compute statistical power analyses for many.
I'm using G*Power to run an a priori power analysis to estimate the sample size for a study I want to run. Formula 1: Using the correlation coefficient Formula 1: If the outcome variable is.
