Is sentinel node biopsy necessary in the radiologically negative axilla in breast cancer? (2019)
Journal Article
Jozsa, F., Ahmed, M., Baker, R., & Douek, M. (2019). Is sentinel node biopsy necessary in the radiologically negative axilla in breast cancer?. Breast Cancer Research and Treatment, 177, 1-4. https://doi.org/10.1007/s10549-019-05299-5

Purpose: The steady move towards axillary conservatism in breast cancer is based on studies demonstrating that axillary node clearance affords no survival benefit in a subset of patients with a positive pre-operative axillary ultrasound (AUS). Howeve... Read More about Is sentinel node biopsy necessary in the radiologically negative axilla in breast cancer?.

Modelling demand for lotto using a novel method of correcting for endogeneity (2019)
Journal Article
Baker, R., Forrest, D., & Perez, L. (2020). Modelling demand for lotto using a novel method of correcting for endogeneity. Economic Modelling, 84, 302-308. https://doi.org/10.1016/j.econmod.2019.04.021

Modelling lottery sales as a function of the mean, standard deviation and
skewness of the probability distribution of returns potentially gives insights into how the
design of a game could be modified to maximise net revenue. But use of OLS is
pro... Read More about Modelling demand for lotto using a novel method of correcting for endogeneity.

New order-statistics-based ranking models and faster computation of outcome probabilities (2019)
Journal Article
Baker, R. (2020). New order-statistics-based ranking models and faster computation of outcome probabilities. IMA Journal of Management Mathematics, 31(1), 33-48. https://doi.org/10.1093/imaman/dpz001

In sport, order-statistics-based models such as Henery’s gamma model and the Thurstone-Mosteller type V model are useful in estimating competitor strengths from observed performance of players in competitions between 2 or more players. They can also... Read More about New order-statistics-based ranking models and faster computation of outcome probabilities.

Objective measures of rollator user stability and device loading during different walking scenarios (2019)
Journal Article
Costamagna, E., Thies, S., Kenney, L., Howard, D., Lindemann, U., Klenk, J., & Baker, R. (2019). Objective measures of rollator user stability and device loading during different walking scenarios. PLoS ONE, 14(1), e0210960. https://doi.org/10.1371/journal.pone.0210960

Walking aids are widely used by older adults, however, alarmingly, their use has been linked to increased falls-risk, yet clinicians have no objective way of assessing user stability. This work aims to demonstrate the application of a novel methodolo... Read More about Objective measures of rollator user stability and device loading during different walking scenarios.

New survival distributions that quantify the gain from eliminating flawed components (2019)
Journal Article
Baker, R. (2019). New survival distributions that quantify the gain from eliminating flawed components. Reliability Engineering and System Safety, 185(May 19), 493-501. https://doi.org/10.1016/j.ress.2019.01.013

A general method for deriving new survival distributions from old is presented. This yields a class of useful mixture distributions. Fitting such distributions to failure-time data allows estimation of the improvement in reliability that could be ga...
