ISRT is delighted to announce that a special issue of the Journal of Statistical Research (JSR) has been published (http://jsr.isrt.ac.bd/jsr-special-issue-vol-55-number-1-2021/). This special issue is to celebrate the 100-year founding anniversary of the University of Dhaka. This milestone anniversary also coincides with two other memorable anniversaries: the 50^th year of independence of Bangladesh and JSR’s 50^th year of publication. ISRT and JSR sincerely acknowledge the funding support from the Centennial Research Grant (CRG) of the University of Dhaka and the dedicated effort of the editorial board members, reviewers, and contributors.
