WebI want to compute the spearman rank correlation using Python and most likely scipy implementation (scipy.stats.spearmanr). The data at hand looks e.g., the following way (dictionaries): {a:0.3, b:0.2, c:0.2} and {a:0.5, b:0.6, c:0.4} To now pass it over to the spearman module, I would assign them ranks, if I am correct (descending): WebAs expected, the correlation coefficient between column two of X and column two of Y, rho(2,2), has the negative number with the largest absolute value (-0.86), representing a high negative correlation between the two columns.The corresponding p-value, pval(2,2), is zero to the four digits shown, which is lower than the significance level of 0.05. ...
