I created an account here trying to get some help on my problem. I'm really desperate as I'm going to need this for my work on my master's degree.

So, here is the problem:

How can I express the function (process) given in pg7 of the article below in simple terms? (something familiar like a sum or a riemman integral)

https://www.stat.washington.edu/research/reports/1994/tr274.pdf

Can anyone help me "decyphering" it? I know that I can take this into a discrete sum of terms depending on my censoring... any tips or any manual for dummies on this?

Thanks,

Júlio
