Abstract

top
The distributions of linear combinations, products and ratios of random variables arise in many areas of engineering. In this note, the exact distributions of α X + β Y , | X Y | and | X / Y | are derived when X and Y are independent normal and logistic random variables. The normal and logistic distributions have been two of the most popular models for measurement errors in engineering.
