Description

########################################################################### Get the parameter values using the Kaplan-Meier survival analysis

Usage

use_km_survival(
  param_to_be_estimated,
  dataset,
  indep_var,
  covariates,
  timevar_survival
)

Arguments

param_to_be_estimated

parameter of interest

dataset

data set to be provided

indep_var

the independent variable (column name in data file)

covariates

list of covariates

timevar_survival

time variable for survival analysis, default is NA

Details

This function is for survival analysis using Kaplan Meier. This plots the cumulative survival function for each combination of covariate If the covariate is numeric, R takes it as different levels. The plot uses the returned list of survfit and extracts the time and the strata from summary of the fit (implemented in plot_return_survival_curve function)

Value

the results of the regression analysis, fit results, summary and plot

Examples

data_for_survival <- survival::aml
surv_estimated <- use_km_survival("status", data_for_survival, "x",
  covariates = NA, "time")
  

data_for_survival <- survival::lung
surv_estimated <- use_km_survival("status", data_for_survival, "sex",
  covariates = c("ph.ecog"), "time")
