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.
