Maximum Likelihood Function
In a previous Hotwire article, we
took a look at probability
plotting. The rank regression or least
squares parameter estimation method essentially "automates" the probability plotting
method mathematically. In this article, we will take a look at the maximum
likelihood estimation (MLE) method. This is considered to be one of the most
robust parameter estimation techniques.

When using the Weibull
distribution, why does it seem that the mean increases as the value of
beta decreases (0 < beta < 1) for a constant value of eta?
Why doesn't BlockSim allow
for the rolling up of system reliability uncertainty
using confidence limits on the individual component parameters?
