Scientific contributions
Professor Khamis presented dozens of scientific papers in statistics and mathematics, and he made important contributions to sampling theory and tabulation of incomplete Gamma functions. In 1966, he published a book entitled : Tables of the Incomplete Gamma Function Ratio .
However, his work is in the field of Index Number Theory and its applications, and his development of what is known as the Geary-Khamis Method to calculate “purchasing power parity (PPP) of currencies. ” It has left its mark on all modern works in the international comparison of prices, real income, national production and productivity using one common currency. The Irish statistician RC Geary was the first to propose the approach in 1952. In 1972, Professor Khamis developed the approach and put it into practice, in a series of scientific papers published in the Journal of the Royal Statistical Society .
The Gerry-Khamis approach has been extensively used for three decades in calculating global inequality, living standards, and estimating the human growth index, and is also used by important international institutions such as the World Bank, the FAO, and the Organization for Economic Co-operation and Development (OECD).
During his life, Professor Khamis received several recognitions and honorary positions from international institutes such as the International Institute of Statistics, which serves as a global academy for statistics, and the American Statistical Association .
In addition to his professional work in the service of humanity, Professor Khamis helped many of his countrymen and other peoples obtain scholarships, and supported many of his students, regardless of their nationalities, in developing their professional lives. He was also known for his strong support for all the causes of the oppressed in the world, and his continued support for Palestinian refugee camps and the Palestinian cause.
