Stop Press: 31 May 2017. These personal pages are presently been updated to include spreadsheet examples described in my book

Non-Standard Parametric Statistical Inference

due to be published shortly by Oxford University Press in June 2017.

 

The Excel examples are here:  Workbooks

This updating will extend past the publication date for the book.

Depending on interest the updating will be ongoing. So if there are examples in the book that have not yet been included here, but which are of particular interest to you, please email me at cheng@btinternet.com

 Research Interests up to 2002

Research and Teaching Interests from 2002, Mainly Connected with Items Involving Various Excel Utilities with VBA code :

Fitting Univariate Distributions:

This link, FittingDistributions, is to an Excel Workbook with VBA modules that can fit various different continuous univariate distributions.

Updated version of Excel Workbook, 17 May 2015: Version14

These include:

gamma distribution (any of up to 3 pars)

Johnson SU (up to 4 pars)

log-gamma distribution ( up to 3 –pars)

normal distribution

Pearson distribution all types

Weibull distribution ( up to 3-pars)

In Version14 also:

            Johnson SB

            lognormal

            Johnson SU

            loggamma

Link to Notes accompanying the workbook: Notes on Distribution Fitting

The workbook can also assess the goodness of fit using the Anderson-Darling test. The critical points are calculated for the model being fitted using bootstrap resampling.

This App is based on my WSC2011 paper downloadable here Cheng2011

Winter Simulation Conference 2009 Introductory Tutorial on Resampling Methods of Analysis in Simulation Studies:

Here is a link to the Proceedings paper with live links: WSC09CC5

Here is a link to a Word file with the text set out in presentation slide format, with active links: WSC09SlideFormatVersion

Fitting Finite Mixture Distributions.  The paper Cheng & Currie 2013 discusses a Bayesian approach to this problem using Importance Sampling. There is an accompanying App in which the approach is implemented. The application is run by an Excel interface. The interface and application in zipped form can be downloaded from here:  FineMix. This is a folder containing all that is needed to use the App. It includes a brief guide.
