Power for Comparing Dependent Coefficients in Multiple Regression with Two or Three Predictors Requires correlations between all variables as sample size. Means, sds, and alpha are option. Also computes Power(All)

1 |

`ry1` |
Correlation between DV (y) and first predictor (1) |

`ry2` |
Correlation between DV (y) and second predictor (2) |

`ry3` |
Correlation between DV (y) and third predictor (3) |

`r12` |
Correlation between first (1) and second predictor (2) |

`r13` |
Correlation between first (1) and third predictor (3) |

`r23` |
Correlation between second (2) and third predictor (3) |

`n` |
Total Sample size |

`alpha` |
Type I error (default is .05) |
