Likewise, the issue of fairness in other sports extensively discussed in the academic literature. DLMA and DLPro models are the special cases of GNLFM.
The GNLFM is a generalization of the Duckworth-Lewis model. Asif and McHale recently proposed a generalized non-linear forecasting model (GNLFM) for LOI cricket. Further, Stern examined the fairness of the DLMA method and reported that only DLPro and DLMA do not violate any of the key principles of fairness as compared to the other alternative methods available in the literature. However, Stern only proposed modification in a parameter of the DLPro model called match factor, denoted by λ. In DLMA, an alternative model for runs to be scored in the remaining innings as a function of overs left and wickets lost was proposed. Stern and McHale and Asif reported that DLPro was not compatible with the modern-age runs scoring pattern. However, these methods had serious shortcomings (see Stern and McHale and Asif for details). In the literature, alternative methods are also proposed, for example, Preston and Thomas, JVD of Jayadevan, Carter and Guthrie, a DL method for Twenty-20 International (T20I) of Bhattacharya et al. In this paper, the McHale and Asif version of the DL method is referred to as DLMA. Recently, Stern had made different modifications in the DLPro method known as Duckworth-Lewis-Stern (DLS) method. In addition, McHale and Asif proposed an improved version of the DL method by changing the functional form of the DL model completely. However, McHale and Asif investigated and examined this modified form of DL method and concluded that the method proposed by Stern violates the basic principles of the game. Stern proposed modification in the DLPro method.

For example, Duckworth and Lewis modified the method, known as then DL Professional Edition (DLPro), so that the method produced fairer adjusted targets in high-scoring interrupted games. Since 1997, attempts had been made to improve the DL method. This version of the DL method is known as Standard Edition. The International Cricket Council (ICC) formally adopted the technique in 1999. , Bailey and Clarke, Asif and McHale ).ĭuckworth and Lewis introduced a method of revising targets for a team batting in the second innings in an interrupted limited-overs match. The DL method is not only used to revise targets but had also used for statistical modelling in cricket (see, for example, Clarke and Allsopp, de Silva et al. Presently, Duckworth-Lewis-Stern method, a modified form of the Duckworth and Lewis proposed by Stern, is in operation by the ICC. In the past, the ICC adopted the Run-Rate method, Most Productive Overs method, Duckworth-Lewis (DL) (Standard and Professional Editions) method. The International Cricket Council (ICC) has sought to have a quantitative method to revise target for a team batting in the second innings so that interrupted matches were concluded with a positive result. Limited Overs International (LOI) was introduced in 1970s.
