confint.segmented.lme | R Documentation |
Computes confidence intervals for all regression parameters, including the the breakpoint, in a fitted ‘segmented mixed’ model.
## S3 method for class 'segmented.lme'
confint(object, parm, level = 0.95, obj.boot, ...)
object |
A fit object returned by |
parm |
A vector of numbers indicating which parameters should be considered. If missing all parameters. |
level |
The confidence level. |
obj.boot |
The possible list including the bootstrap distributions of the regression coefficients. Such list is returned by |
... |
if |
If obj.boot
is provided or ...
includes the argument B>0
, confidence intervals are computed by exploiting the bootstrap
distributions.
A matrix (or a list of matrices if bootstrap ci are requested) including the confidence intervals for the model parameters.
All the functions for segmented mixed models (*.segmented.lme) are still at an experimental stage
