ctsem (version 2.1.0)

ctStanContinuousPars: ctStanContinuousPars

Description

Returns the continuous time parameter matrices for specified subjects of a ctStanFit fit object

Usage

ctStanContinuousPars(ctstanfitobj, subjects = "all", iter = "all", calcfunc = quantile, calcfuncargs = list(probs = 0.5))

Arguments

ctstanfitobj

fit object from ctStanFit

subjects

Either 'all', or integers denoting which subjects to perform the calculation over. When multiple subjects are specified, the returned matrices will be a mean over subjects.

iter

Either character string 'all' which will then use all post-warmup iterations, or an integer specifying which iteration/s to use.

calcfunc

Function to apply over samples, must return a single value. By default the median over all samples is returned using the quantile function, but one might also be interested in the mean or sd, for instance.

calcfuncargs

A list of additional parameters to pass to calcfunc. For instance, with the default of calcfunc = quantile, the probs argument is needed to ensure only a single value is returned.

Examples

#posterior median over all subjects (also reflects mean of unconstrained pars)
ctStanContinuousPars(ctstantestfit)

#posterior 95% quantiles for subject 2
ctStanContinuousPars(ctstantestfit, subjects=2, calcfunc=quantile, 
calcfuncargs=list(probs=0.95))
