Description

Compute power for a One Factor ANOVA with three levels and contrasts. Takes means, sds, and sample sizes for each group. Alpha is .05 by default, alternative values may be entered by user

Usage

anova1f_3c(
  m1 = NULL,
  m2 = NULL,
  m3 = NULL,
  s1 = NULL,
  s2 = NULL,
  s3 = NULL,
  n1 = NULL,
  n2 = NULL,
  n3 = NULL,
  alpha = 0.05,
  c1 = 0,
  c2 = 0,
  c3 = 0
)

Arguments

m1	Mean of first group
m2	Mean of second group
m3	Mean of third group
s1	Standard deviation of first group
s2	Standard deviation of second group
s3	Standard deviation of third group
n1	Sample size for first group
n2	Sample size for second group
n3	Sample size for third group
alpha	Type I error (default is .05)
c1	Weight for Contrast 1 (default is 0)
c2	Weight for Contrast 2 (default is 0)
c3	Weight for Contrast 3 (default is 0)

Value

Power for the One Factor ANOVA

Examples

anova1f_3c(m1=80, m2=82, m3=82, s1=10, s2=10, s3=10,
n1=60, n2=60, n3=60, c1=2, c2=-1, c3=-1, alpha=.05)
