x
Vector of parameters, ordered as follows: Scale parameter, Shape parameter, regression parameters (i.e. $\beta$) linked to the non-censored covariates, regression parameter (i.e. $\beta$) linked to the censored covariate.
data_y
Time-to-event vector.
data_delta_loglik
Censored indicator vector of the time-to-event (0: censored, 1: not censored).
data_cov_noncens
Matrix where each column represents a non-censored covariate.
data_cov_cens
Censored covariate vector.
density
Density function of the censored covariate.
data_r_loglik
Censored indicator vector of the censored covariate (0: censored, 1: not censored).
data_lowerbound
A vector which corresponds to the lower bounds for the interval-censored observations of the censored covariate. If no lower bound is available then put NA.
intlimit
In computation of integrals, values of the function to be integrated below intlimit are set to 0. This makes integration results more accurate and speeds up integration. If the data is such that the absolute values of the underlying baseline
