Find sample size given a power 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

findRMSEAsamplesizenested(rmsea0A = NULL, rmsea0B = NULL, rmsea1A,
  rmsea1B = NULL, dfA, dfB, power = 0.8, 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.
power	The desired statistical power.
alpha	The alpha level.
group	The number of group in calculating RMSEA.
