London-based Royal Statistical Society said in statement: “Frank will be remembered largely for his contributions to Society as editor of RSS News, and to cricket as co-inventor of Duckworth-Lewis method.” Duckworth introduced short paper, titled ‘A fair result in foul weather’ at an RSS conference in 1992.
