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)

## Arguments

x numeric vector 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

## Value

a numeric vector of length(x).

## Examples

 xg <- seq(-5, 5, length.out=101)
plot(xg, invprobit(xg, rho=-2, zeta=-0.3))
