hidimLasso: hidimLasso

LASSO for high dimensional data

Description

Least Absolute Shrinkage and Selection Operator (LASSO) for High Dimensional Survival data.

Usage

hidimLasso(m, n, OS, Death, data)

Arguments

m

Starting column number from where variables of high dimensional data will get selected.

n

Ending column number till where variables of high dimensional data will get selected.

OS

Column name of survival duration event, a string value. i.e. "os"

Death

Column name of survival event, a string value. i.e "death"

data

High dimensional data having survival duration, event and various covariates observations

Value

A list of variables selected by LASSO as predictor variables.

Details

'HiDimLasso' allows a user to apply LASSO function on the High Dimensional data and reduce the study variables to handful number of co-variate which are observed impacting the survival outcomes.

Column of Overall Survival must be named as 'OS' and the column defining the event must be named as 'Event'.

By default it stores the outcome data in user's current directory.
