About Me

Imdadullah: Admin and Author of gmstat.com

I am Muhammad Imdad Ullah, the Author and Admin of gmstat.com. In 2017, I earned my Ph.D. degree in Statistics from Bahauddin Zakariya University Multan, Pakistan. The main concentration of my work in my Ph.D. was detection and collinearity and its remedy using some biased regression techniques such as ridge regression and Liu regression. I proposed two collinearity diagnostics in my Ph.D. work and also developed three R packages that are available on CRAN. The packages are mctest, lmridge, and liureg. I also have three publications related to these packages in The R Journal.

I am also teaching applied Statistics and Mathematics as a visiting lecturer in different departments of the University.
