Using Fife, Hunter, and Mendoza's (2013) Case III-R correction,
`caseIIIR`

corrects the tp correlation for direct restriction on x (and
by implication, indirect restriction on x)

1 | ```
caseIIIR(data.matrix = NULL, rtp, rsp, rts, SR)
``` |

`data.matrix` |
a data matrix with rows representing observations and columns representing variables. Note: no observations should be present when using case III-R. |

`rtp` |
the restricted correlation between t (the predictor variable) and p (the outcome variable). |

`rsp` |
the restricted correlation between s (the suitability variable) and p (the outcome variable). |

`rts` |
the restricted correlation between t (the predictor variable) and s (the suitability variable). |

`SR` |
the selection ratio (i.e., the proportion of applicants who were selected) |

later

a scalar that is the unbiased estimate of the correlation between T and P.
