Distribution

The oversight and process to control the acquisition, analysis, storage, retrieval, and distribution of data.

A distribution containing infinite (variable) data points that may be displayed on a continuous measurement scale (e.g., normal, exponential, or Weibull).

A homogeneous group of data which are independent and randomly distributed in one common distribution.

A statistical study of the relationship between two or more variables. Regression analysis is a process used to define the mathematical relationship or model between two or more variables. When analyzing time-to-failure data, this is commonly called Weibull analysis in which one may or may not attempt to fit a Weibull distribution to the data.

The mathematical and/or graphical analysis of time-to-failure data of items in use by customers. Analysis of field data enables an estimate of the actual field time-to-failure distribution or failure rate.
