Consulting
I am very interested in applications of probability and statistics
to industry and business.
The main companies for whom I have consulted are in the nuclear sector and include
AMECNSS, Nuclear Safety
Solutions, Ontario Power Generation,
Ontario Hydro, and the CANDU Owners Group, but I have also done work for
the Ontario Lottery and Gaming
Corporation, the Western Canada Lottery Corporation, Fallsview Casino, the Canadian
Nuclear Safety Commission, Monserco,
Ontario Workplace Safety Insurance
Board, Kraft Foods, Nestles, and the Ontario College of
Respitatory Therapists, as well as various law firms.
I welcome queries from the public.
Lotteries
Since the Maclean's Magazine article appeared, quoting my calculations for Lotto, and comparing the chance of winning to the chance of tossing 24 heads in a row (This description covered Lotto 6/49 at the time. It needs to be updated for the new prize structure.) I have often been contacted by the media when there is lottery fever or some lottery question. This happened most recently in October 2006 the day of a CBC Fifth Estate program concerning allegations of fraud by lottery retailers. I was quoted by the Toronto Star as saying that no more than about 20 retailers should have won major prizes. (This story even appeared in the Canadian Chinese press.)
I computed this number based on the information given to me by both the Star and CHTV. My understanding was that the figures supplied applied only to Lotto Super 7 and my estimate therefore only applied to this particular lottery. Unfortunately, this information was omitted from the article, but happily, the article did say that my conclusion "depend[ed] on assumptions made about how many retailers play the lottery."

Chance
Chance is an outstanding source of probability and statistics ideas as applied to everyday life to which I've occasionally contributed items with pedagogic value. Here are four that would be of interest to high school and university students.
Excel
I am a strong proponent of the use of Excel in teaching undergraduate statistics. Even in my
consulting, I have found
Excel to be a handy tool for scientists and engineers for examining data, plotting, and suggesting
models. Of course, Excel does have some known problems, for instance in simulation. I have written a
number of macros for use in my Statistics 1cc3 classes at McMaster University.
This archive of macros
accompanies the 4th edition of my Excel Manual for The Basic Practice of Statistics, W. H. Freeman, NY,
2006 used in conjunction with
David Moore's popular The Basic Practice of Statistics, W. H. Freeman, NY, 2006.
The regression to the mean macro S1cc3_corr.xls
simulates 1000 pairs of observations (x, y)
from a population with a correlation given by a parameter "rho" (Greek letter).
It draws the line of equal percentiles and also the regression line.
The user can change the value of rho with the slider. Each time the sample is taken,
the value of the correlation r computed from the sample is shown. Observe that
r is close to rho but does vary from sample to sample. Repeated use of
macro shows how scatterplots with different correlations might appear.
The sampling simulation macro samsim.xls showing histograms of 1000 SRSs of size
100 from a population. User can change the population proportion.
The macro gbmsim.xls simulates stock market prices using geometric Brownian motion.
If you have any questions or suggestions for other macros please
contact me. (If you encounter a runtime error in the boxplot
macro using the RUN button, then access the macro from the menu
Tools > Macros > bp open_dialog_box.)
