Twenty20 cricket.

Cricket has been a very popular sport around the world. But since most versions of cricket take longer to play than other popular sports, cricket is likely to be affected by unfavourable weather conditions. In 1998, Duckworth and Lewis developed a method for resetting the target scores for the team batting second in interrupted one-day cricket. Twenty20 is the latest form of cricket. Currently, the Duckworth-Lewis method is also used for resetting targets in interrupted Twenty20 matches. However, this may be less than ideal since the scoring pattern in Twenty20 is much more aggressive than that in one-day cricket. In this project, we consider the use of the Duckworth-Lewis method as an approach to reset target scores in interrupted Twenty20 matches. The construction of the Duckworth-Lewis table is reviewed and alternate resource tables are presented for Twenty20. Alternative resource tables are constructed in a nonparametric fashion using two different approaches.
