Linear functions of random variables
NettetInvertible functions. In the case in which the function is neither strictly increasing nor strictly decreasing, the formulae given in the previous sections for discrete and continuous random variables are still applicable, provided is one-to-one and hence invertible. We report these formulae below. One-to-one functions of a discrete random variable http://web.math.ku.dk/~rolf/teaching/FM2_10/OnLognormals.pdf

The Function Identification Problem. The function identification problem can be made precise in a number of ways. For the purpose of the present paper, we phrase it in a probabilistic manner. We consider a multivariate distribution of ( n + 1 ) random variables, denoted by X = ( X 1 , X 2 , … , X n ) T and Y .
Nettet2. feb. 2024 · Perhaps you can call them "linear transformations of binomail distributions". EDIT based on comment by whuber: That said, it's not to hard to write out a formula for the probability mass function, P ( Y = y) = P ( a ⋅ X + b = y) and then just plugin the probability mass function for X after inverting the equation.
