optimization_time_data: Time Dependent Optimization Data

In herglola/SVHM: Support-Vector-Hazard-Machine

Time Dependent Optimization Data

Description

calculates all needed values to execute quadratic optimization for the time dependent SVHM at the given event time.

Usage

optimization_time_data(covariates, mat_train, event_time, gamma_squared = 0.5)

Arguments

covariates	dataset of covariates of the subjects in a dataset
mat_train	matrix of all individuals under risk at the event time
event_time	event time for which data is calculated
gamma_squared	width of gaussian kernel

Value

List $adap_k_mat matrix on which quadratic optimization will be performed $w_vec vector of weights at any event time for all subjects $k_mat Gram matrix of covariates $e_vec vector indicating vector containing information if a subject experiences an event.
