plotRMSEApowernested: Plot power of nested model RMSEA

Description

Plot power of nested model RMSEA over a range of possible sample sizes.

Usage

plotRMSEApowernested(rmsea0A = NULL, rmsea0B = NULL, rmsea1A,
  rmsea1B = NULL, dfA, dfB, nlow, nhigh, steps = 1, 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

nlow

Lower bound of sample size

nhigh

Upper bound of sample size

steps

Step size

alpha

The alpha level

group

The number of group in calculating RMSEA

…

The additional arguments for the plot function.
