Weibullmodeller
Weibullmodeller refers to a family of probability distributions widely used in reliability engineering, survival analysis, and quality control. The most common is the two-parameter Weibull distribution. Its flexibility allows it to model a variety of failure patterns, including increasing, decreasing, and constant hazard rates. The probability density function (PDF) of the two-parameter Weibull distribution is given by f(x; k, lambda) = (k/lambda) * (x/lambda)^(k-1) * exp(-(x/lambda)^k), where x is the variable of interest (e.g., time to failure), k is the shape parameter, and lambda is the scale parameter.
The shape parameter, k, dictates the form of the failure rate. If k < 1, the failure rate
In addition to the two-parameter model, a three-parameter Weibull distribution exists, which includes a location parameter
