The shape parameter, k, is that power plus one, and so this parameter can be interpreted directly as follows: [6] A value of k < 1 {\displaystyle k<1\,} indicates that the failure rate decreases over time (like in case of the Lindy effect , which however corresponds to Pareto distributions [ 7 ] rather than Weibull distributions).
A what if chart (Whif chart, WHIF analysis, etc.) is a visual tool for modeling the outcome of a combination of different factors.The table can represent actual results or predicted outcome based on combinations of parameters.
In statistics, a power transform is a family of functions applied to create a monotonic transformation of data using power functions.It is a data transformation technique used to stabilize variance, make the data more normal distribution-like, improve the validity of measures of association (such as the Pearson correlation between variables), and for other data stabilization procedures.
