Webmedian correlation between two 1d sets of the same length. We define this correlation similarly to Pearson, as cosine of an angle between two normalised samples of numbers, interpreted as coordinate vectors. Pearson first normalises each set by subtracting its mean from all components. WebIn the mixedCor function, you tell R which variables are numeric, binary, and ordinal and it …
