Pearsonr x and y must have length at least 2

WebSep 15, 2024 · Pearson Correlation formula: x and y are two vectors of length n m, x and m, y corresponds to the means of x and y, respectively. Note: r takes value between -1 (negative correlation) and 1 (positive correlation). r = 0 means no correlation. Can not be applied to ordinal variables. The sample size should be moderate (20-30) for good estimation. WebHere, you use np.arange () to create an array x of integers between 10 (inclusive) and 20 (exclusive). Then you use np.array () to create a second array y containing arbitrary integers. Once you have two arrays of the …
