Distributions not available in the stats package

Family objects provide a convenient way to specify the details of the models used by functions such as stats::glm(). These functions within this package are not available within the stats package but are designed in a similar manner.

Usage

lognormal(link = "log")

multinomial(link = "logit")

Arguments

link

A string specifying the model link function. For example, "identity" or "log" are appropriate names for the stats::gaussian() distribution. "log" and "logit" are the defaults for the lognormal and the multinomial, respectively.

Value

An object of class family (which has a concise print method). This particular family has a truncated length compared to other distributions in stats::family().

family

character: the family name.

link

character: the link name.
