In semPower: Power Analyses for SEM

semPower.powerPlot.byN

Description

Shows a plot showing power as function of N for a given effect and alpha.

Usage

semPower.powerPlot.byN(
  effect = NULL,
  effect.measure = NULL,
  alpha,
  df,
  p = NULL,
  SigmaHat = NULL,
  Sigma = NULL,
  power.min = alpha,
  power.max = 0.99,
  steps = 50,
  linewidth = 1
)

Arguments

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
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. Use in conjunction with ⁠Sigma`` to define ⁠effectandeffect.measure'.
Sigma	population covariance matrix. Use in conjunction with SigmaHat to define effect and effect.measure.
power.min	minimum power, must not be smaller than alpha.
power.max	maximum power
steps	number of steps
linewidth	linewidth

Value

powerplot
