findRMSEApowernested

Find power given a sample size in nested model comparison

Description

Find the sample size that the power in rejection the samples from the alternative pair of RMSEA is just over the specified power.

Usage

findRMSEApowernested(rmsea0A = NULL, rmsea0B = NULL, rmsea1A,
  rmsea1B = NULL, dfA, dfB, n, alpha = 0.05, group = 1)

Arguments

`rmsea0A`	The H_0 baseline RMSEA
`rmsea0B`	The H_0 alternative RMSEA (trivial misfit)
`rmsea1A`	The H_1 baseline RMSEA
`rmsea1B`	The H_1 alternative RMSEA (target misfit to be rejected)
`dfA`	degree of freedom of the more-restricted model
`dfB`	degree of freedom of the less-restricted model
`n`	Sample size
`alpha`	The alpha level
`group`	The number of group in calculating RMSEA
