WebThis metric measures the correlation between a pair of numerical columns and computes the similarity between the real and synthetic data -- aka it compares the trends of 2D distributions. This metric supports both the Pearson and Spearman's rank coefficients to measure correlation. WebThe Jaro similarity of two given strings and is Where: is the length of the string ; is the number of matching characters (see below); is the number of transpositions (see below). Jaro similarity score is 0 if the strings do not match at all, and 1 if they are an exact match.

WebSep 6, 2024 · The Jaro similarity metric between two strings a and b is defined as follows, where m is the number of matching characters, and where t is half the number of character transpositions in the strings. Two characters from strings a and b are considered to match if they are equal and if they are not farther than characters apart. WebThe Levenshtein distance ( method='lv') counts the number of deletions, insertions and substitutions necessary to turn b into a. This method is equivalent to R 's native adist function. The Optimal String Alignment distance ( method='osa') is like the Levenshtein distance but also allows transposition of adjacent characters.
