SUMMARY

The discussion centers on the concept of determining the expected value of N in a random number generation (RNG) scenario where an integer is uniformly selected from 1 to N. The user QM seeks to identify the specific terminology associated with this type of problem, which is related to the German tank problem. This problem involves estimating the total number of items based on observed samples, particularly in the context of random sampling.

PREREQUISITES
  • Understanding of random number generation (RNG) principles
  • Familiarity with statistical estimation techniques
  • Knowledge of the German tank problem and its applications
  • Basic probability theory concepts
NEXT STEPS
  • Research the German tank problem and its mathematical foundations
  • Explore statistical methods for estimating population parameters from samples
  • Learn about uniform distribution and its implications in RNG
  • Study the concept of expected value in probability theory
USEFUL FOR

Mathematicians, statisticians, data scientists, and anyone interested in probability theory and statistical estimation techniques.

TL;DR
A RNG picks an integer uniformly from 1 to N. It picks 4. What is the expected value of N?
Hey all,

So this time I have a different kind of question - namely, "what is this called?"
I recall hearing/reading this in at least two places, one of which was YouTube. The idea is the following:
A RNG picks an integer uniformly from 1 to N. It picks 4. What is the expected value of N?
I'm pretty sure I know how to solve this problem. My question is the following: Is there a name for this problem, or problems like it? Where the parameters of the random number generator are the thing you're trying to determine?

Cheers,
QM
