Sample siza planning for population root mean square error of approximation

Description

Sample siza planning for population root mean square error of approximation from the Accuracy in Parameter Estimation (AIPE) perspective

Usage

ss.aipe.rmsea(RMSEA, df, width, conf.level = 0.95)

Arguments

RMSEA population root mean square error of approximation
df degrees of freedom of the model
width desired confidence interval width
conf.level desired confidence level (e.g., .90, .95, .99)

Value

Returns the necessary total sample size in order to achieve the desired degree of accuracy (i.e., the sufficiently narrow confidence interval).
