unihdaftma {autohd}R Documentation

High dimensional competing risk analysis by univariate accelerated failure time model with mediation analysis

Description

Given the dimension of variables and survival information risks the function filters significant variables, allowing the user to fit univariate AFT model. Further, it performs mediation analysis among the significant variables and provides handful variables with their alpha.a values which are mediator model exposure coefficients and beta.a coefficients.

Usage

unihdaftma(m, n, survdur, event, ths, b, d, data)

Arguments

m

Starting column number from where high dimensional variates to be selected.

n

Ending column number till where high dimensional variates to be selected.

survdur

"Column/Variable name" consisting duration of survival.

event

"Column/Variable name" consisting survival event.

ths

A numeric between 0 to 100.

b

Number of MCMC iterations to burn.

d

Number of draws.

data

High dimensional data containing survival observations and high dimensional covariates.

Value

Data frame containing the beta and alpha values of active variables among the significant variables.
