In szugat/predfat: What the package does (short line)

Computation of fitted values for new data

1	getFit(newdata, theta, lambda, type, plot = FALSE, median = FALSE)

`newdata`	values of influental variable
`theta`	parameter vector for link function
`lambda`	[`function(theta, x)`] link function for exponential distribution
`type`	[`integer`] if link function is not given a collection of given link function is available, see `linkfun`
`plot`	logical value indicating whether the fitted values should be added to an existing plot
`median`	logical value indicating whether the median (TRUE) oder the expectation should be fitted (FALSE, default)
