This is an inner wrapper for the C++ functions which perform the E step and is not intended to be used directly.
This function does not check the input.
For a data set with K clusters,
Estep(c, c_lt, delta, alpha, bbeta, pvfm, dist)Vector of length K of cumulative hazards, i.e. total accumulated hazards within a cluster
Vector of length K of cumulative hazard from 0 to the left truncation time
Vector of integers of length K of the number of events for each cluster
Parameters of the frailty distribution
Parameter for the PVF distribution, only matters in that case
One of 0 (for gamma), 1 (for stable) or 2 (for PVF)
A K x 3 matrix where the first column and the second column are the numerators
and the denominators of the frailty fraction (without the Laplace transform) and the
last column is the log(denominator) + log-Laplace transform, i.e. the log-likelihood contribution
