If by correlation you mean a measure of goodness-of-fit of a specific class of curves (like Pearson correlation for linearly related variables), you can use Pearson correlation for non-normal data. As you can read here, the normality assumption for Pearson correlation is important for the calculation of p-value and confidence intervals.

WebThe correlation coefficient r is a unit-free value between -1 and 1. Statistical significance is indicated with a p-value. Therefore, correlations are typically written with two key numbers: r = and p = . The closer r is to zero, the weaker the linear relationship. Positive r values indicate a positive correlation, where the values of both ... WebIn terms of SciPy’s implementation of the beta distribution, the distribution of r is: dist = scipy.stats.beta(n/2 - 1, n/2 - 1, loc=-1, scale=2) The default p-value returned by pearsonr is a two-sided p-value. For a given sample with correlation coefficient r, the p-value is the probability that abs (r’) of a random sample x’ and y ... WebStatistics is the science of analyzing, reviewing and conclude data.
