Analyze Mayo Clinic Primary Biliary Cirrhosis, Sequential Data

Use the pbc dataset (https://stat.ethz.ch/R-manual/R-devel/library/survival/html/pbcseq.html) to identify an important variable in a time to event context.

First, assess the normality of each of the candidate variables and create a table showing the appropriate summary statistics ( e.g. mean +- sd or median)

Then, create a standard Cox regression model for survival using each of the variables. Then use LASSO regression to identify a parsimonious set of variables predictive of survival. Propose what you believe to be the best model for the prediction of survival.
