Discover what a log-normal distribution is, its financial applications, and how to calculate it, including using Excel for ...

A t-distribution is a type of probability function that is used for estimating population parameters for small sample sizes or unknown variances.

In this note it is shown that P (η - ξ > 0) can easily be calculated using tables of the bivariate normal distribution, where ξ, η are independent, ξ has a normal distribution, and η has a truncated ...

For each problem, a normal-based approximate procedure is outlined, and its applicability and validity for a gamma distribution are studied using Monte Carlo simulation. Our investigation shows that ...
