Dataframe T20_table has one row for each T20 IPL match in the
period 2008-2017 with the exception of seven drawn matches and three
no-result matches which were removed. Object T20 is a
likelihood function for the strengths of the 13 teams, and
T20_toss is a likelihood function that also includes a toss
strength term.
These objects can be generated by running script inst/T20.Rmd,
which is based on Chandel and Hankin 2019. This includes some further
discussion and technical documentation and creates file T20.rda
which resides in the data/ directory.
