fd_term {SIMICO}

d/d_theta_l

Description

Calculate the first derivative of the theta terms for outcome l.

Usage

fd_term(l, temp_beta, phen,d, apply_diffs,
   A_i, no_l_all,HL_array, HR_array)

Arguments

l

Outcome of interest.

temp_beta

Vector of fitted coefficients.

phen

list containing the covariate design matrices.

d

Number of quadrature nodes.

apply_diffs

Matrix containing the differences between survival functions of the left and right time intervals.

A_i

Product of apply_diffs across all outcomes k summed over all quadrature nodes d.

no_l_all

n x (k - 1) matrix containing the product of apply_diffs across all outcomes k excluding the current outcome l.

HL_array

n x k matrix containing all the hazard values for the left times.

HR_array

n x k matrix containing all the hazard values for the right times.

Value

The output is a 1 x (p + 2) vector of the first derivative terms for outcome l.
