An outlier in an independent samples design (2018)
Presentation / Conference
Derrick, B. (2018, September). An outlier in an independent samples design. Paper presented at Royal Statistical Society Conference

There is a flaw with some of the most commonly performed statistical tests. A paradox of the one sample t-test is the contrariwise decrease in the p-value as the value of an outlier increases in the direction of the overall effect. Demonstration of t...

To preliminary test or not to preliminary test, that is the question (2018)
Presentation / Conference
Derrick, B. (2018, July). To preliminary test or not to preliminary test, that is the question

Despite the consequences of violations to the assumptions of statistical tests, there is often neglect in published works to report on the assumptions of the tests performed. Preliminary testing the assumptions prior to preforming the test is done ro... Read More about To preliminary test or not to preliminary test, that is the question.

A comparison of analytical methods for the two group pre- post design (2017)
Presentation / Conference
Allis, V., & White, P. (2017, April). A comparison of analytical methods for the two group pre- post design. Poster presented at UWE Student Conference

Simulation demonstrates that for a two group randomized design ANCOVA is more powerful than the gain score approach For ANCOVA with an interaction term the model with pre scores X as a covariate is more powerful than the model with X + Y as the co...

Multiuser scheduling on the LTE downlink with simulated annealing (2011)
Presentation / Conference
Aydin, M. E., Kwan, R., Wu, J., & Zhang, J. (2011, May). Multiuser scheduling on the LTE downlink with simulated annealing. Presented at 2011 IEEE 73rd Vehicular Technology Conference (VTC Spring)

In this paper, the issue of multi-user radio resource scheduling on the downlink of a Long Term Evolution (LTE) cellular communication system is addressed. An optimization model has been proposed in [1], where radio resources for multiple users are j... Read More about Multiuser scheduling on the LTE downlink with simulated annealing.
