# anova1f_4c: Compute power for a One Factor ANOVA with four levels. Takes... In pwr2ppl: Power Analyses for Common Designs (Power to the People)

## Description

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

## Usage

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19``` ```anova1f_4c( m1 = NULL, m2 = NULL, m3 = NULL, m4 = NULL, s1 = NULL, s2 = NULL, s3 = NULL, s4 = NULL, n1 = NULL, n2 = NULL, n3 = NULL, n4 = NULL, alpha = 0.05, c1 = 0, c2 = 0, c3 = 0, c4 = 0 ) ```

## Arguments

 `m1` Mean of first group `m2` Mean of second group `m3` Mean of third group `m4` Mean of fourth group `s1` Standard deviation of first group `s2` Standard deviation of second group `s3` Standard deviation of third group `s4` Standard deviation of forth group `n1` Sample size for first group `n2` Sample size for second group `n3` Sample size for third group `n4` Sample size for fourth 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) `c4` Weight for Contrast 4 (default is 0)

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10``` ```anova1f_4c(m1=80, m2=82, m3=82, m4=86, s1=10, s2=10, s3=10, s4=10, n1=60, n2=60, n3=60, n4=60, c1=1, c2=1, c3=-1, c4=-1, alpha=.05) anova1f_4c(m1=80, m2=82, m3=82, m4=86, s1=10, s2=10, s3=10, s4=10, n1=60, n2=60, n3=60, n4=60, c1=1, c2=-1, c3=-0, c4=0, alpha=.05) anova1f_4c(m1=80, m2=82, m3=82, m4=86, s1=10, s2=10, s3=10, s4=10, n1=60, n2=60, n3=60, n4=60, c1=0, c2=0, c3=1, c4=-1, alpha=.05) #'@return Power for the One Factor ANOVA ```
