Multivariate normal distribution
It works for values of $k$ other than two. Multiplying every element of a matrix by $2π$ can be rephrased as multiplying every row of the matrix by $2π$. In particular, that will multiply the determinant by $(2π)^{k}$ where $k$ is the number of rows. Because the determinant is then raised to the power −1/2 this delivers the desired factor of $(2π)^{−k/2}$. Would you undo your undo? 𝕃eegrc (talk) 16:53, 17 November 2016 (UTC)
