14 дек. 2023 г. · If a transformation of a random variable preserves its mean and variance, can it change the covariance with another random variable? [closed].

26 мая 2024 г. · I understand the calculations quite well, and I spent some time on the linked page understanding the derivation of the formula itself.

6 нояб. 2020 г. · If we have a random variable having standard normal distribution (mean = 0 and var = 1) then its square is chi-square distribution with 1 degree of freedom.

14 мая 2024 г. · I'm new to probability and I want to know the general formula for calculating the mean and variance of a transformed random variable.
