Congratulations Peijun Sang, 2019 Pierre Robillard award recipient!

Peijun Sang

The Statistical Society of Canada (SSC) awarded Peijun Sang as the winner of the 2019 Pierre Robillard Award of the Statistical Society of Canada. This prize recognizes the best PhD thesis in probability or statistics defended at a Canadian university in a given year. Peijun’s thesis, entitled “New Methods and Models in Functional Data Analysis" was written while he was a doctoral student at the Simon Fraser University, working under the supervision of Jiguo Cao.

His current research interests are focused on functional data analysis methods. Data from electroencephalogram signals, function magnetic resonance imaging and diffusion tensor imaging are important examples. He is interested in applying functional data analysis techniques to study functional connectivity between imaging data collected from different regions of the brain. He is concerned with large sample properties of high dimensional functional regression models that have been proposed for this type of data. He is also interested in dependence modelling with copulas for discrete and time-to-event outcomes.

Mu Zhu Elected Fellow of the American Statistical Association

Mu Zhu

Professor Mu Zhu of Department of Statistics and Actuarial Science at University of Waterloo is elected Fellow of the American Statistical Association (ASA). The citation reads: “For outstanding research contributions to statistical learning in recommender systems, ensemble approaches to variable selection, unbalanced classification and rare target detection; and service to the profession.”

The designation of ASA Fellow has been a significant honor for nearly 100 years. Under ASA bylaws, the Committee on Fellows can elect up to one-third of one percent of the total association membership as fellows each year.

The 2019 class of ASA Fellows will be formally presented at the award session at this year’s Joint Statistical Meetings in Denver, Colorado.

Stocks 10 to 20 years old could be in investment sweet spot

Researchers have discovered that stocks listed on the market for between 10 and 20 years could be in a sweet spot for investment. 

The new study from the University of Waterloo suggests that investing in stocks listed on the market for between 10 and 20 years could – on average – increase your expected returns.

“It is widely believed that smaller companies generally outperform larger companies on the stock market,” said Tony Wirjanto, a professor jointly appointed in Waterloo’s School of Accounting and Finance and Department of Statistics and Actuarial Science. “But we have found that in the last 20 years, the age of a stock has a much more profound effect on the expected return. The idea is that you shouldn’t just look at the size, but the age of the stocks, if you actually want to do well on the market.”
