# Capability/Performance & Distribution Analysis - Form

This form will perform Capability Analysis, Performance Analysis, and Distribution Analysis.

## Distribution Analysis

This form will allow you to fit you data to the following distributions.

**None**— No distribution fit.**Normal**— The data is fit with a Normal distribution.**Exponential (0)**— The data is fit with an Exponential distribution, using "0" as the lower bound.**Exponential (Low)**— The data is fit with an Exponential distribution, using lowest value as the lower bound.**Weibull (2 Param)**— The data is fit with a 2-Parameter Weibull distribution.**Uniform**— The data is fit with a Uniform distribution.**Johnson**— The data is fit with a Johnson Distribution, S_{U}, S_{B}, or S_{L}.**Gamma (0)**— The data is fit with a Gamma distribution, using "0" as the lower bound.**Gamma (Low)**— The data is fit with a Gamma distribution, using lowest value as the lower bound.**Beta**— The data is fit with a Beta distribution.**Rayleigh(0)**— The data is fit with a Rayleigh distribution, using "0" as the lower bound.**Rayleigh(Low)**— The data is fit with a Rayleigh distribution, using the lowest value as the lower bound.

## Capability Analysis

When specifications are entered, a distribution fit is selected, and the Capability is checked, the following table will be displayed.

## Performance Analysis

When specifications are entered and the Performance is checked, the following table will be displayed.

## Probability Plot

When the Probability Plot tab is selected the following will be displayed.

When the Linear checkbox is checked the plot will be linearized as follows.

## Distribution Calculations

When the Distribution Calculations button is clicked, the following form will be displayed. This form will display observed and calculated tail-areas, or values for a given proportion.
