Biography

My research focuses on developing methods and software for eliciting expert knowledge as prior distributions in Bayesian statistics, under the supervision of Dr. Fadlalla Elfadaly.

Softwares for Prior Elicitation:

  1. Elicitation of Univariate Distributions over [0,1] for Binomial Sampling Models
  2. PEDMB: Prior Elicitation of a Dirichlet Distribution with Marginal Betas
  3. PEDCCB: Prior Elicitation of a Dirichlet and Connor–Mosimann Distribution with Conditional Betas
  4. PEGCM: Prior Elicitation for a Gaussian Copula using Different Marginals
  5. PEVCM: Prior Elicitation for a Vine Copula using Different Marginals
  6. PEDGMS: Prior Elicitation of Dirichlet Generalisations for Multinomial Sampling models
  7. PERMI: Prior Elicitation of Regression Models on the Unit Interval
  8. PEBSI: Prior Elicitation for Binomial Sampling models on the Unit Interval
