In September 2000,the Executive Board of the Islamic Society of Statistical Science
Awarded a gold medal to Professor Syed Ejaz Ahmed in recognition of his contributions
To the statistical literature and his interest in the advancement of Statistics,which has motivated Pakistanis,in particular,and Muslim statisticians,in general,to undertake research in this discipline.As a further acknowledgement of his scholarly work and dedication,the Board mandated the publication of this specila issue of the Pakistan Journal of Statistics.
