Marginal log likelihood function of the nonparametric multinomial with censoring and truncation

Description

Marginal log likelihood function of the nonparametric multinomial with censoring and truncation

Usage

np_nll(par, cens_lb, cens_ub, trunc_lb, trunc_ub, cens, trunc, weights)

Arguments

par	vector of D-1 parameters
cens_lb	index of interval in which death occurs
cens_ub	index of interval in which death occurs (if death is observed), or else the largest interval.
trunc_lb	vector of largest index for the lower truncation
trunc_ub	vector of smallest index for the upper truncation

Value

a scalar, the negative log likelihood value
