/* MostFrequentTerm ( theList ) v1.0 • 30 November 2021 • Toronto by Brian Panhuyzen Neutrino Data Systems https://neutrinodata.com Yields the most frequent term from a list of values. Will work only with FileMaker 18 or later, since it uses the recursive While function. */ While ( [ i = 0 ; ~Result = "" ] ; i < ValueCount ( theList ) ; [ i = i + 1 ; ~Result = Let ( ~Term = GetValue ( theList ; i ) ; If ( not PatternCount ( ~Result ; ~Term ) ; List ( ~Result; ~Term ) ; List ( ~Term; Substitute ( ~Result ; ~Term & ¶ ; "" ) ) ) ) ] ; GetValue ( ~Result ; 1 ) ) Click to copy

Provide the function with a list of values that includes repeating terms, and it will yield the most frequently occurring term. A tie in most-frequent terms (e.g., two or more terms occur with the same frequency) will result in only the latest term in the list appearing.

The function can be adapted to show a list of all the terms in order of diminishing frequency by removing the GetValue function for the ~Result.
