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.

Tool Tips |
|
|
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?
