Distribution of minimum of random variables

Click For Summary
SUMMARY

The discussion focuses on the joint distribution function of two independent random variables, X and Y, specifically for U=min(X,Y) and V=max(X,Y). The initial confusion was clarified when it was established that X and Y are independent random variables, simplifying the derivation of the marginal distributions for U and V. The participant initially proposed a joint distribution expression of 2[u(v-u) + ½u^2], which indicates an understanding of the relationship between the minimum and maximum of the random variables.

PREREQUISITES
  • Understanding of joint distribution functions
  • Knowledge of independent random variables
  • Familiarity with minimum and maximum functions in probability
  • Basic concepts of marginal distributions
NEXT STEPS
  • Study the properties of joint distribution functions for independent random variables
  • Learn how to derive marginal distributions from joint distributions
  • Explore the concept of order statistics in probability theory
  • Investigate applications of minimum and maximum distributions in statistical analysis
USEFUL FOR

Statisticians, data scientists, and students studying probability theory who are interested in understanding the distribution of minimum and maximum values of random variables.

anyone's help would be really appreciated. I can't figure out that one.

If X and Y are joint random variables, what is the joint distribution funtion of U=min(X,Y) and V=max(X,Y).

I got something like 2[u(v-u) + ½u^2)]

then how do i worked towards and expression for the marginal distribution of U and V?

sorry my mistake.. they are independent rv... now the question is quite simple! thanks anyway! :blushing:
 
Anytime! :smile:
