When performing market basket analysis, the following type of error may occur:
“No rule was found. Smaller minimum support or minimum confidence might find rules.”
There was 1 warning in dplyr::mutate().
In argument: processed = purrr::map(…). Caused by warning in arules::apriori(): ! Mining stopped (maxlen reached).
In many cases, this error occurs because no extractable rules were found with the current minimum support or minimum confidence settings.
You can often avoid this issue by changing Selection of Minimum Support Value to “Specity Value” and lowering the minimum values for support and confidence in the analytics settings.
However, if the error persists even after lowering the minimum support and confidence values, it is likely that there are no extractable rules present in your data.
