My research develops flexible probability distributions and empirical likelihood methods for survival analysis, with a focus on improving statistical inference for biomedical data under small-sample and complex settings. It integrates distribution theory and likelihood-free inference, with applications in biomedical research and reliability studies.

About Me

I am a Master's student in Applied Statistics with a concentration in Biostatistics at Georgia State University, working under the supervision of Prof. Yichuan Zhao. My work centres on developing statistical models and likelihood-free inference methods for biomedical survival data, particularly in small-sample settings.

My current work introduces the Quadratic-Transformed Exponential-Gamma (QTEG) distribution and extends it using jackknife empirical likelihood methods to achieve likelihood-free inference, particularly in small-sample biomedical settings.

I hold a Master of Professional Studies in Analytics (Statistical Modeling) from Northeastern University, Toronto, Canada (2025), and an M.Sc. in Statistics from Ekiti State University, Nigeria (2021), where I served as an Assistant Lecturer supervising over 40 undergraduate research projects. I also hold a B.Sc. in Statistics from Ekiti State University (2016). I am a Fellow of the Commonwealth Academy of Leadership and Management (FCALM), UK.

My long-term goal is to develop advanced statistical methodology that integrates distribution theory, empirical likelihood, and biomedical and public health applications.

Research

My thesis constitutes a three-stage methodological program building from distribution development through advanced inference to model validation, with each stage grounded in biomedical survival analysis.

Stage 01
QTEG Distribution
Quadratic transformation framework for flexible lifetime distributions based on the exponential-gamma family, applied to biomedical survival data.
Under Review · Statistical Papers
Stage 02
Empirical Likelihood Extension
JEL and AJEL confidence interval methods using survival-based estimating equations — a likelihood-free inference framework for biomedical time-to-event data.
In Progress
Stage 03
Goodness-of-Fit Testing
Goodness-of-fit testing via characterisation-based U-statistics within the empirical likelihood framework for validating biomedical survival models.
Proposed
Distribution Theory

The QTEG Distribution

Introduces a new class of flexible lifetime distributions based on a quadratic transformation of the exponential-gamma model, designed for modelling skewed and heavy-tailed biomedical survival data with tractable statistical properties.

Statistical Inference

Jackknife Empirical Likelihood

Develops jackknife empirical likelihood (JEL and AJEL) methods as a likelihood-free inference framework for parameter estimation, improving accuracy for biomedical time-to-event data under small-sample conditions.

Model Validation

Goodness-of-Fit via U-Statistics

Proposes a goodness-of-fit testing framework based on characterisation-driven U-statistics within the empirical likelihood paradigm, providing a formal tool for validating distributional assumptions in biomedical survival analysis.
