+\description{Create \code{\link[depmix]{response}} models.}
+\usage{
+
+ GLMresponse(formula, family, data, pstart=NULL, fixed=NULL)
+
+ transInit(formula, family=multinomial(), data, nstates,
+ pstart=NULL, prob=TRUE, fixed=NULL)
+
+ \S4methods{npar}{response}(object)
+}
+\arguments{
+ \item{object}{An object of class \code{response} or one of its
+ descendents.}
+ \item{formula}{A model formula.}
+ \item{family}{A family object; currently only multinomial() and
+ gaussian() are allowed options.}
+ \item{data}{An optional data.frame to interpret the variables from the
+ formula argument in.}
+ \item{pstart}{Starting values for the coefficients and other
+ parameters, ie the standard deviation for the gaussian() family.}
+ \item{fixed}{Logical vector indicating which paramters are to be fixed.}
+ \item{prob}{Logical indicating whether the starting values for
+ multinomial() family models are probabilities or logistic
+ parameters (see details).}
+}
+\details{
+
+ Both methods use the familiar formula interface from linear and general
+ linear models to specify how responses (or transition or prior
+ parameters) depend on covariates.
+
+ The GLMresponse model is an interface to the glm functions of which
+ the functionality is leant, ie predict, fit and density functions.
+
+ The transInit response model provides functionality for multinomial
+ responses that are currently fit using nnet (this may change in the
+ future but this should not affect the interface of this function). Note
+ that the transInit model actually lacks a reponse, ie the y-slot is
+ empty, at the time of construction, as the transitions are not
+ observed.
+
+}
+\value{
+ \code{GLMresponse} and \code{transInit} return objects of class
+ \code{GLMresponse} and \code{transInit} respectively; both classes
+ extend the \code{\link[depmix]{response-class}}.
+
+ Objects with class \code{response} have at least methods: \code{predict}
+ to return \code{predict}'ed responses, \code{dens} to return the
+ \code{dens}'ity of responses.
