Hi,

please am looking for someone to help me to answer this discussion questions for my two class..thanks

The question and other materials required are attached below.

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.

Next, use an interesting R package you find online to identify any variables that may be non-linearly associated with the time to event outcome. 

Finally, create an interesting figure that you feel adequately displays and demonstrates the information that you have found.
