Transform Split Hazard Code from Stata into Text and Formulas

Job ID: 35816336

Budget: €30 – €250 EUR

I have an old split hazard code in Stata which I programmed over 10 years ago. I haven't touched it since. I simply cannot remember which specific model I implemented and why I made the model choices.
Now I was asked to transform this code into written text and formulas, so that it is easy to understand.
I need someone who helps me translate this code into a text and formulas equivalent to the example.
