Events for 13 March 2017

Hana Alqifari: Nonparametric predictive inference for future order statistics.

12:00am, CM221

In this talk I will present nonparametric predictive inference (NPI) for future order statistics, including joint probabilities for multiple future order statistics. We develop and illustrate several statistical inference methods in terms of future order statistics, including pairwise and multiple comparisons and reproducibility of statistical tests based on order statistics. Reproducibility of statistical hypothesis tests is an issue of major importance in applied statistics: if the test were repeated, would the same conclusion be reached about rejectance of the null hypothesis? NPI provides a natural framework for such inferences, as its explicitly predictive nature fits well with the core problem formulation of a repeat of the test in the future. For inference on reproducibility of statistical tests, NPI provides lower and upper reproducibility probabilities (RP) of some tests based on order statistics, namely a population quantile test and a basic precedence test.

Najla Qarmalah: Using Mixture Models for Prediction from Time Series, with Application to Energy Use Data

2:30pm, CM221

Locally weighted mixture models are used for predictions which have been employed for analysing the trends of time series data. Estimation of these models are achieved through a kernel-weighted version of the EM-algorithm,using exponential kernels with different bandwidths which have a much bigger effect on the accuracy of the forecast than the choice of kernel. By modelling a mixture of local regressions at a target time point but with different bandwidths, the estimated mixture probabilities are informative for the amount of information available in the data set at the scale of resolution corresponding to each bandwidth. Nadaraya-Watson and local linear estimators are used to carry out the localized estimation step. Then, several approaches for many step ahead predictions at a time point from these models are investigated with different bandwidths. Real data are provided including data on energy use of some countries from 1971 to 2011.

Efthymios Sofos : Some problems on the distribution of prime and square-free numbers

4:00pm, CM107

I will talk about some number theory problems that I am currently interested in. These include the distribution of prime and square-free integers, as well as solutions of Diophantine equations in the primes.
