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
See Also
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)
