Thiele made notable contributions to the statistical study of random time series and introduced the cumulants and likelihood functions, and was considered to be one of the greatest statisticians of all time by Ronald Fisher.[2] In the early 1900s he also developed and proposed a generalisation of approval voting to multiple winner elections called sequential proportional approval voting,[3] which was briefly used for party lists in Sweden when proportional representation was introduced in 1909.
