We wish you every success in the exciting journey ahead!

What makes the ISI Regional Statistics Conference 2026 truly valuable?

It’s the people.

From 3–5 June 2026 in Valletta, Malta, statisticians and data scientists will come together to connect, share knowledge, and learn from each other. Bringing together professionals from different regions and backgrounds, from academia and official statistics to industry and policy, the conference creates a welcoming space for conversations, new ideas, and meaningful collaborations that continue beyond the conference.

What you can expect:
• 300+ participants
• 3 inspiring conference days
• 200+ scientific talks
• Excellent networking opportunities

We invite you to join us in Malta to connect, share, and learn.

⏳ Early Bird registration available until 15 March

On the 27th January 2026, the Department of Statistics was proud to be represented by Dr. Monique Borg Inguanez at the St Aloysius College Sixth Form University Orientation Visits.
Dr. Borg Inguanez introduced students to the fascinating fields of Statistics and Operations Research, explaining how these disciplines help us understand uncertainty, optimize decisions, and solve real-world problems. She also outlined the courses offered by the department, and shared examples of the diverse career paths available to graduates—from data science and analytics to roles in finance, healthcare, and government.

We’re delighted to support students as they explore their future studies, and we thank St Aloysius College for the invitation!

A Big congratulations to our Statistics and Operations students graduates! Hard work and perseverance certainly pay off! Good luck for for future.

The Department of Statistics and Operations Research is pleased to announce a talk by Professor Suresh Sethi from the University of Texas at Dallas.

Title: Hierarchical and Mixed Leadership Games for Dynamic Supply Chains: Applications to Cost Learning and Co-op Advertising

Date: Tuesday 11 November 2025

Time: 10:00 - 12:00

Venue: MP 405

Abstract:

We consider two applications of dynamic stochastic supply chains.

The first application is a decentralised two-period supply chain in which a manufacturer produces a product with cost learning benefits and sells it through a retailer facing price-dependent demand. The manufacturer’s second-period production cost declines linearly in the first-period production, but with a random learning rate. The manufacturer may or may not have the inventory carryover option. We formulate the problem as a two-period Stackelberg game and obtain its feedback equilibrium solutions explicitly. We then examine the impact of the mean learning rate and learning rate variability on channel members' pricing strategies, the manufacturer’s production decisions, and the retailer’s procurement decisions. We show that as the mean learning rate or the learning rate variability increases, the traditional double marginalisation problem becomes more severe, leading to greater efficiency loss in the channel. We obtain revenue-sharing contracts that can coordinate the dynamic supply chain.

The second application studies a novel manufacturer-retailer cooperative advertising game where, in addition to the traditional setup into which the manufacturer subsidises the retailer's advertising effort, we also allow the reverse support from the retailer to the manufacturer. This is modelled as a mixed leadership game in which one player is a leader on some decisions and a follower on other decisions. We find an equilibrium that can be expressed by a solution of a set of algebraic equations. We then conduct an extensive numerical study to assess the impact of model parameters on the equilibrium.

Representing your fellow students is a valuable and rewarding opportunity. By taking part, you’ll not only help shape the future of your faculty/institute/centre/school (F/I/C/S), but you’ll also gain important skills and experiences that will benefit you in your academic journey and future career.

Take the chance to make a difference, build leadership skills, and have your voice heard!
