London: Frank Duckworth, one half of the team, who pioneered the Duckworth-Lewis method for calculating target scores in limited-overs cricket matches abridged by bad weather, has died at the age of 84.

Along with his fellow statistician Tony Lewis, Duckworth devised the formula that was officially adopted by the International Cricket Council in 1999 and remains the means by which affected matches are decided.

The Royal Statistical Society (RSS) said in a statement: “Fellows will be sad to learn that Frank Duckworth passed away on 21 June 2024, at the age of 84.

“Frank will be remembered largely for his contributions to the Society as Editor of RSS News, and to cricket as the co-inventor of the Duckworth Lewis method,” it said.
