asr_families {asreml}R Documentation

GLM family objects for asreml.

Description

Family functions specify the details of the models accepted by the family argument to asreml.

Usage

asr_gaussian(link = "identity", dispersion = NA)

asr_Gamma(link = "inverse", dispersion = 1, phi = 1)

asr_inverse.gaussian(link = "1/mu^2", dispersion = NA)

asr_binomial(link = "logit", dispersion = 1, total = NULL)

asr_multinomial(link = "logit", dispersion = 1, total = NULL)

asr_negative.binomial(link = "log", dispersion = 1, phi = 1)

asr_poisson(link = "log", dispersion = 1)

Arguments

link

A character string identifying the link function; valid values are:

Gaussian:

identity, log, inverse

Gamma:

identity, log, inverse

inverse.gaussian:

1/mu^2, identity, log, inverse

binomial:

logit, probit, cloglog

multinomial:

logit, probit, cloglog

negative.binomial:

identity, log, inverse

poisson:

identity, log, sqrt

dispersion

If NA, the default for Gaussian and inverse Gaussian models, the dispersion parameter is estimated, otherwise it is fixed at the nominated value (default 1.0).

phi

The known value of the additional parameter phi.

total

A character string or name giving the column in data containing the total counts.

Value

A list of functions and expressions needed by the family argument.
