FBD - "Find the Best Distribution" tool

With this GUI you can find the best distribution that fits your data.

Description

1. Save the Main_FitDistribution_GUI.fig and Main_FitDistribution_GUI.m files at the same directory.
2. Run the Main_FitDistribution_GUI.m file.
3. Load data using the "Load Data" button. The file should be a text file with 1 column containing the data. The attached file "DataExample.txt" contains data in a legal format.
4. choose whether you want to fit continuous of discrete distributions, and whether you want to display the PDFs of the CDFs (with the pop-down menus). The lists of optional distributions are displayed on the left side of the GUI.
5. Press "FIT!"
6. You will see the 4 best fits on the graph, and detailed parameters of the best 4 distributions under the graph. The parameters are:
- Distribution name.
- NLogL - Negative of the log likelihood.
- BIC - Bayesian information criterion.
- AIC - Akaike information criterion.
- AICc - AIC with a correction for finite sample sizes.
- Parameters names.
- Parameters values.

A good one. You may want to consider to use Scott Hirsch's submission which allows you to interactively select variables from the workspace.

It gives you more flexibility than using files.
