profile.fwdtr.object

Description

An object containing the values of the profile log-likelihood for each transformation parameter specified in function fwdtr. The class attribute is set to profile.fwdtr.

Format

A profile.fwdtr.object is a list with the following elements:

call
the matched call.
lambda
a sequence of values from bounds[1] to bounds[2] with step 0.1. This vector will contain the x-coordinates of the profile log-likelihoods
profile
a list containing the values of the profile log-likelihoods for each variable. First element of the list is associated with first variable and so on.
ci
a list containing the lower and upper values of the confidence intervals for each variable. First element of the list is associated with first variable and so on.
x.names
a character vector containing the names of the columns which are investigated for transformation.
step.fwd
a scalar containing the step of the forward search for which the profile log-likelihoods are computed.
onepar
logical. If TRUE a common value lambda has been used for estimation
p
an integer, the number of variables in the data.
Mle
a vector containing the maximum likelihood estimates of the transformation parameters at step step.fwd of the forward search.

Details

Class profile.fwdtr object is created by function profile.fwdtr

fwdtr
computes maximum likelihood estimates of transformation parameters in each step of the forward search.
fwdtrProfilePlot
Plot profile loglikelihoods of transformation parameters in a selected step of the forward search

Examples

 

data(mussels.dat)

## Forward search on untrasformed data 
## Compute max lik. estimates of tramsformation parameters

l.mle<-fwdtr(mussels.dat)

## Compute profile loglikelihoods for transformation parameters in the last step of the search 
## and create an object of class profile.fwdtr

l.profile.mle <- profile.fwdtr(l.mle)

## plot the profile loglikelihoods of transformation parameters for each variable

fwdtrProfilePlot(l.profile.mle)
