Distribution Analyzer

Distribution Analyzer is a shareware software package for identifying a distribution that best fits a set of data and for estimating expected ranges for future values. It provides a means of performing Normal Tolerance Intervals (K-intervals) and Variables Sampling Plans on data that does not fit the normal distribution. The Analysis performed includes: Selection of Best Fit Distribution and Estimation of Parameters Test of Whether Selected Distribution Adequately Fits the Data Determination of a Transformation (Function) That Can be Applied to Data so that Transformed Data Fits the Normal Distribution Construction of Tolerance Intervals Including a Specified Percentage of the Future Values (Normal Tolerance Interval) Confidence Statements for Percentage of Future Values in Spec (Variables Sampling Plan) Take an example of break force values show below. There is a lower spec limit of 4 pounds:
