SOBE Research Colloquium featuring Zarrukh Rakhimov

On October 8, 2025, Westminster International University in Tashkent (WIUT) hosted a research colloquium featuring Zarrukh Rakhimov, PhD candidate in Econometrics and Statistics, who presented his study titled " Bootstrap Confidence Intervals in Linear Models”.

The research explored the reliability of bootstrap confidence intervals in linear regression analysis, particularly in situations where classical model assumptions—such as normality and homoscedasticity—do not hold. Using a series of Monte Carlo simulations, he compared bootstrap techniques with traditional OLS-based intervals, demonstrating that bootstrap methods often provide more consistent and robust inference under non-ideal data conditions.

The discussion highlighted the practical value of bootstrap approaches for researchers working with small samples or irregular data patterns. After several discussions, his research was approved to move to the next stage of development.

After several discussions, his dissertation was recommended to proceed to the next stage of defense/VIVA according to Supreme Attestation committee requirements.

Scientific Seminar

On 19th of September 2025, Westminster International University in Tashkent held discussions on two dissertations in the specialty 08.00.06 – Econometrics and Statistics:

Alisher Suyunov presented his dissertation on “Econometric Modelling of Labour Market Patterns: Job Creation and Job Destruction.” His research provides econometric insights into labor market dynamics, with a focus on the processes of job creation and destruction.

Olmas Isakov presented his dissertation on “Improving Econometric and Statistical Bases for Credit Risk Assessment in Credit Institutions.” The study offers methodological contributions to enhance risk assessment practices in financial institutions through advanced econometric and statistical tools.

Based on the outcomes of the seminar, the following dissertations were recommended for defense at the Scientific Council DSc.22/30.12.2019.I.85.01 on awarding academic degrees at Westminster International University in Tashkent.

SOBE Research Colloquium featuring Sanemkhan Nurillaeva

On May 28, 2025, the School of Business and Economics (SOBE) at WIUT hosted a research colloquium featuring Sanemkhan Nurillaeva, a PhD candidate in Management.

Her presentation, titled "Improving the Mechanisms of Corporate Social Responsibility in Commercial Banks of the Republic of Uzbekistan," focused on enhancing the effectiveness of CSR initiatives within the country's banking sector. The research highlighted current challenges, regulatory gaps, and proposed practical frameworks to align CSR practices with international standards while addressing local socio-economic needs.

The session drew strong interest from faculty and students, sparking meaningful discussion on the evolving role of banks in promoting sustainable development and social accountability in Uzbekistan.

SOBE Research Colloquium featuring Mekhruza Vafokulova

On June 18, 2025, Westminster International University in Tashkent (WIUT) hosted a research colloquium featuring Vafokulova Mekhruza, PhD candidate in Management, who presented her study titled "Transforming Local Economies through Family-Run Tourism Enterprises: A Socio-Economic Management Perspective in Uzbekistan."

The research examined the socio-economic role of family-run tourism businesses in Uzbekistan, focusing on their impact on employment generation, income creation, and regional development. Despite their growing importance in the national tourism economy, empirical evidence on their management practices and economic influence remains limited.

The presentation offered valuable insights into the potential of family enterprises to contribute to inclusive economic growth and sparked an engaging discussion among attendees on the future of community-based tourism in Uzbekistan. Valuable recommendations were suggested to PhD candidate in order to improve the quality of the dissertation.

SOBE Research Colloquium featuring Zarrukh Rakhimov

On May 27, 2025, Westminster International University in Tashkent (WIUT) hosted a research colloquium featuring Zarrukh Rakhimov (PhD candidate in "Econometrics and statistics"), who presented his research study titled "Bootstrap Confidence Intervals in Linear Models."

The presentation focused on the reliability of bootstrap confidence intervals in linear regression analysis, especially under conditions where classical assumptions—such as normality, homoscedasticity, or complete data—may be violated. Using Monte Carlo simulations, Rakhimov compared traditional OLS-based intervals with various bootstrap methods across multiple challenging data environments, including small samples, outliers, and missing data not at random (MNAR).

Particular attention was given to the “bootstrap pairs” technique, which showed strong performance in delivering consistent interval coverage when traditional assumptions did not hold. The findings suggest that bootstrap methods can serve as a valuable alternative or complement to standard techniques, especially in empirical research involving imperfect or non-ideal data.

The session generated keen interest among faculty, researchers and students, providing practical insights for improving statistical inference in applied research.
