Provide a detailed procedure to perform the following in python

$$

$$ Perform four sets of experiments: $($i$)$ simulated survival data, $($ii$)$ real survival data, $($iii$)$ simulated treatment data, and $($iv$)$ real treatment data.

$$ Use simulated data to show how IPTW and the G$-$Formula successfully model survival probabilities using pseudo values.

$$ Validate IPTW and the G$-$Formula predictive ability by training them on real survival data.

$$ Simulate treatment data to verify that IPTW and the G$-$Formula to obtain $$multiple survival probabilities

$$Evaluation $$ To evaluate the models$$ predictive accuracy on the survival data, $$measure the concordance$-$index $($C$-$index$)$ c as outlined by
