Impute Interval Censored Data from icenReg Regression Model
Description
Imputes censored responses from data.
Usage

Arguments

icenReg model fit |
newdata |
|
imputeType |
type of imputation. See details for options |
samples |
Number of imputations (ignored if |
Details
If newdata
is left blank, will provide estimates for original data set.
There are several options for how to impute. imputeType = 'median'
imputes the median time, conditional on the response interval, covariates and
regression parameters at the MLE. To get random imputations without accounting
for error in the estimated parameters imputeType ='fixedParSample'
takes a
random sample of the response variable, conditional on the response interval,
covariates and estimated parameters at the MLE. Finally,
imputeType = 'fullSample'
first takes a random sample of the coefficients,
(assuming asymptotic normality) and then takes a random sample
of the response variable, conditional on the response interval,
covariates, and the random sample of the coefficients.
