The deviance residual for the th observation is where the plus (minus) in is used if is greater (less) than . The deviance is the sum of squares of the deviance residuals. DFBETAS
WebJun 15, 2024 · I already broke down the formula of the calculation of v = csum * rsum * (n - rsum) * (n - csum) / n**3 into the terms cr_sum = csum * rsum and n_rcsum = (n - rsum) * (n - csum). Both output arrays have the shape (2,5). It seems to be necessary to calculate the Hadamard Product of cr_sum and n_rcsum here. Webresiduals = [Y [i] - y_hat [i] for i in range (len (Y))] We need to find H matrix which is where X is the matrix of our independent variables. To find leverage, we have to take the diagonal elements of H matrix, in the following way: leverage = numpy.diagonal (H) Find Standard Error if regression as

WebMay 13, 2024 · The Pearson correlation coefficient (r) is the most common way of measuring a linear correlation. It is a number between –1 and 1 that measures the strength and direction of the relationship between two variables.
