Use the pbc dataset (https://stat.ethz.ch/R-manual/R-devel/library/survival/html/pbcseq.html) to determine an vital variable in a time to occasion context.
First, assess the normality of every of the candidate variables and create a desk displaying the suitable abstract statistics ( e.g. imply +- sd or median)
Then, create an ordinary Cox regression mannequin for survival utilizing every of the variables. Then use LASSO regression to determine a parsimonious set of variables predictive of survival. Suggest what you consider to be the perfect mannequin for the prediction of survival.
Subsequent, use an fascinating R package deal you discover on-line to determine any variables that could be non-linearly related to the time to occasion consequence.
Lastly, create an fascinating determine that you just really feel adequately shows and demonstrates the data that you’ve got discovered.
