 Wavelet-based Analysis in Gaussian Processes Regression

  • ​Developing a moment-based estimation procedure using wavelet variance and the Generalized Method of Wavelet Moments (GMWM), achieving scalable log-linear complexity O(log⁡(n)n).


 Dynamic Copula Models for Portfolio Optimization 

  • Devising semiparametric model that combines non-parametrically estimated copulas with parametrically estimated marginals to allow all parameters to dynamically evolve over time. 

 

 Bioequivalence testing under privacy constraints 

  • Developing differentially private equivalence testing procedure using a simulation-based method to construct
    confidence intervals.

Mixed Effects Models (MEM) for Crossover Data
• Devised methods for analyzing crossover trials with incomplete or skewed data distributions using MEM.
• Applied Monte Carlo Expectation Maximization (MCEM) within MEM for maximum likelihood estimation of parameters with missing or skewed data.
•  Illustrated statistical modelling and estimation using gene expression data from a 3 ×3 crossover study.

Clustering Multiple Time-series Data
•  Developed model-based gene expression time series clustering using MEM and non-parametric Dirichlet processes to capture temporal effects.
•  Analyzed gene expression data from antibiotic-producing Streptomyces coelicolor using these techniques.
