Find the sample size that the power in rejection the samples from the alternative pair of RMSEA is just over the specified power.
findRMSEAsamplesizenested(rmsea0A = NULL, rmsea0B = NULL, rmsea1A, rmsea1B = NULL, dfA, dfB, power=0.80, alpha=.05, group=1)
rmsea0A |
The H0 baseline RMSEA. |
rmsea0B |
The H0 alternative RMSEA (trivial misfit). |
rmsea1A |
The H1 baseline RMSEA. |
rmsea1B |
The H1 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 |
