Calculate the values of the sigmoidal function that is defined by the
cumulative normal distribution function (
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)
numeric vector of length 1 or the same length as x. Specifies the inflection point of the inverse probit curve.
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.
boolean if the log of the result is returned
boolean if one minus the result is returned
a numeric vector of
