Details

This function calculates the Readability Index (RIX) by Anderson, which is a simplified version of the l\"asbarhetsindex (LIX) by Bj\"ornsson. In contrast to readability, which by default calculates all possible indices, this function will only calculate the index value.

This formula doesn't need syllable count.
