Calculate the values of the sigmoidal function that is defined by the
cumulative normal distribution function (`pnorm`

). This
method provides a convenient wrapper for the `pnorm`

that automatically
handles negative zeta and is more consistent in its naming.

invprobit(x, rho, zeta, log = FALSE, oneminus = FALSE)

x | numeric vector |
---|---|

rho | numeric vector of length 1 or the same length as x. Specifies the inflection point of the inverse probit curve. |

zeta | numeric vector of length 1 or the same length as x. Specifies the scale of the curve at the inflection point of the inverse probit curve. |

log | boolean if the log of the result is returned |

oneminus | boolean if one minus the result is returned |

a numeric vector of `length(x)`

.
