Python array as a counter

How to find the probability of extinction = 1 using Galton-Watson process in R?

QUESTION

Python array as a counter

Asked 2022-Jan-26 at 14:19

I'm a Python 3.0 beginner and I'm struggling to find a solution to the following problem. It's a step for a Galton Board simulation exercise.

I have an numpy array, which length is auto generated based on another variable
I am then generating a set of numbers, adding them to a list and summing them
I would finally want to add a counter of +1 to the array index, which equals the number in the sum in step 2.

QUESTION

How to find the probability of extinction = 1 using Galton-Watson process in R?

Asked 2021-Apr-29 at 20:19

I am simulating a basic Galton-Watson process (GWP) using a geometric distribution. I'm using this to find the probability of extinction for each generation. My question is, how do I find the generation at which the probability of extinction is equal to 1?

For example, I can create a function for the GWP like so:

I can tell you how you would do this problem in principle, but I'm going to suggest that you may run into some difficulties (if you already know everything I'm about to say, just take it as advice to the next reader ...)

theoretically, the Galton-Watson process extinction probability never goes exactly to 1 (unless prob==1, or in the infinite-time limit)
of course, for any given replicate and random-number seed you can compute the first time point (if any) at which all of your lineages have gone extinct. This will be highly variable across runs, depending on the random-number seed ...
the distribution of extinction times is extremely skewed; lineages that don't go extinct immediately will last a loooong time ...

I modified your GWP function in two ways to make it more efficient: (1) stop the simulation when the lineage goes extinct; (2) replace the sum of geometric deviates with a single negative binomial deviate (see here)
