`caseIV`

uses Hunter and Schmidt's (2004) correction procedure to
estimate the correlation between t and p, assuming direct selection on a
latent s.

1 | ```
caseIV(rtpi, rxxi, rxxa, ux)
``` |

`rtpi` |
the correlation between t and p in the incumbent pool. |

`rxxi` |
the reliability of x in the incumbent pool. |

`rxxa` |
the reliability of x in the applicant pool. |

`ux` |
the ratio of selected to unselected variance in x. |

a scalar that is the estimate of the correlation between t and p.
