Time-varying ratings for international football teams (2017)
Journal Article
Baker, R., & McHale, I. (2017). Time-varying ratings for international football teams. European Journal of Operational Research, 267(2), 659-666. https://doi.org/10.1016/j.ejor.2017.11.042

We present a model for rating international football teams. Using data from 1944 to 2016, we ask `which was the greatest team?'. To answer the question requires some sophisticated methodology. Specifically, we have used k-fold cross-validation, whi... Read More about Time-varying ratings for international football teams.

An adjusted random-effects model for binary-data meta-analysis (2017)
Journal Article
Baker, R. (2017). An adjusted random-effects model for binary-data meta-analysis. Statistics and Probability Letters, 134, 93-97. https://doi.org/10.1016/j.spl.2017.10.018

A new model with a variable size of random effect is introduced for the meta-analysis of 2 times 2 tables. The random-effects parameter has a simple interpretation in terms of sample size and offers a new measure of heterogeneity.

High intensity focused ultrasound in the treatment of breast fibroadenomata (HIFU-F trial) (2017)
Journal Article
Peek, M., Ahmed, M., Scudder, J., Baker, R., Charalampoudis, P., Pinder, S., & Douek, M. (2017). High intensity focused ultrasound in the treatment of breast fibroadenomata (HIFU-F trial). International Journal of Hyperthermia, 34(7), 1002-1009. https://doi.org/10.1080/02656736.2017.1373865

Background: High intensity focused ultrasound (HIFU) is a non-invasive ablative technique utilising the application of high frequency ultrasound (US) pressure waves to cause tissue necrosis. This emerging technology is currently limited by prolonged... Read More about High intensity focused ultrasound in the treatment of breast fibroadenomata (HIFU-F trial).

Event count distributions from renewal processes : fast computation of probabilities (2017)
Journal Article
Baker, R., & Kharrat, T. (2017). Event count distributions from renewal processes : fast computation of probabilities. IMA Journal of Management Mathematics, 29(4), 415-433. https://doi.org/10.1093/imaman/dpx008

Discrete distributions derived from renewal processes, i.e. distributions of the number of events by some time t are beginning to be used in management science, econometrics and health sciences. A new fast method is presented for computation of the p... Read More about Event count distributions from renewal processes : fast computation of probabilities.

Meta-analysis of tumour burden in pre-operative axillary ultrasound positive and negative breast cancer patients (2017)
Journal Article
Ahmed, M., Jozsa, F., Baker, R., Rubio, I., Benson, J., & Douek, M. (2017). Meta-analysis of tumour burden in pre-operative axillary ultrasound positive and negative breast cancer patients. Breast Cancer Research and Treatment, 166(2), 329-336. https://doi.org/10.1007/s10549-017-4405-3

Management of the axilla in breast cancer is becoming increasingly conservative. Patients identified with a low axillary nodal burden (two or fewer involved nodes) at sentinel node biopsy (SNB) can avoid completion axillary node clearance (cANC). 'Fa...

Paule-Mandel estimators for network meta-analysis with random inconsistency effects (2017)
Journal Article
Jackson, D., Veroniki, A., Law, M., Tricco, A., & Baker, R. (2017). Paule-Mandel estimators for network meta-analysis with random inconsistency effects. Research Synthesis Methods, 8(4), 416-434. https://doi.org/10.1002/jrsm.1244

Network meta-analysis is used to simultaneously compare multiple treatments in a single analysis. However, network meta-analyses may exhibit inconsistency, where direct and different forms of indirect evidence are not in agreement with each other, ev...

Creating new distributions by blunting cusps (2017)
Journal Article
Baker, R. (2017). Creating new distributions by blunting cusps. Statistics and Probability Letters, 124, 55-63. https://doi.org/10.1016/j.spl.2017.01.003

A simple method is proposed for `blunting' cusped distributions, ie removing the cusp. No additional parameters are required. The method is applied to the asymmetric Laplace distribution, to the van Dorp and Kotz double-sided power distribution, an... Read More about Creating new distributions by blunting cusps.
