)

Arguments

power.type	type of power analyses, one of "a-priori", "post-hoc", "compromise", "powerplot.byN", "powerplot.byEffect"
effect	effect size specifying the discrepancy between H0 and H1
effect.measure	type of effect, one of "F0", "RMSEA", "Mc", "GFI", "AGFI"
alpha	alpha error
beta	beta error
power	power (= 1 - beta)
abratio	ratio alpha/beta
N	the number of observations
df	the model degrees of freedom
p	the number of observed variables, required for effect.measure = "GFI" and effect.measure = "AGFI"
SigmaHat	model implied covariance matrix
Sigma	observed (or population) covariance matrix
muHat	model implied mean vector
mu	observed (or population) mean vector
simulatedPower	whether to perform a simulated (TRUE) (rather than analytical, FALSE) power analysis.
modelH0	for simulated power: lavaan model string defining the (incorrect) analysis model.
power.min	for plotting: minimum power
power.max	for plotting: maximum power
effect.min	for plotting: minimum effect
effect.max	for plotting: maximum effect
steps	for plotting: number of sampled points
linewidth	for plotting: linewidth
