Fit Distributions<br />

Table 2.16 Description of Fit Distribution Options (Continued)<br />

Save Density Formula<br />

Save Spec Limits<br />

Save Transformed<br />

Remove Fit<br />

Creates a new column in the current data table that contains fitted<br />

values that have been computed by the density formula. The density<br />

formula uses the estimated parameter values.<br />

Saves the specification limits as a column property. See “Statistical<br />

Details for Fit Distribution Options” on page 84.<br />

Creates a new column <strong>and</strong> saves a formula. The formula can<br />

transform the column to normality using the fitted distribution. This<br />

option is available only when one of the Johnson distributions or the<br />

Glog distribution is fit.<br />

Removes the distribution fit from the report window.<br />

Diagnostic Plot<br />

The Diagnostic Plot option creates a quantile or a probability plot. Depending on the fitted distribution,<br />

the plot is one of four formats.<br />

Table 2.17 Descriptions of Plot Formats<br />

Plot Format<br />

Applicable Distributions<br />

The fitted quantiles versus the data • Weibull with threshold<br />

• Gamma<br />

• Beta<br />

• Poisson<br />

• GammaPoisson<br />

• Binomial<br />

• BetaBinomial<br />

The fitted probability versus the data • Normal<br />

• Normal Mixtures<br />

• Exponential<br />

The fitted probability versus the data on log scale • Weibull<br />

• LogNormal<br />

• Extreme Value
