Each slice along the third dimension would be one of your n-by-2 matrices which you called B1, B2, B3, etc. One can then compare the true statistic to the generated distribution of null statistics. With n 5 rows in A you would get 14,400 different B matrices and that is too many to dream up names for, so I have put them all into a single n-by-2-by- (n)2 array which I call B. Trace of Matrix is the sum of main diagonal elements of the matrix.Main Diagonal also known as principal diagonal is the diagonal which connects upper left element bottom right element. This function permutes rows and columns of a matrix using the specified permutation vector. A permutation test involves permuting one or more variables in a data set before performing the test, in order to break any existing relationships and simulate the null hypothesis. After converting a 1D array to a 2D array or matrix in the above example, the items. According to the definition given on page 449 of the book Discriminants, Resultants, and Multidimensional Determinants, the output of this method is $s'(M)$, where $s'$ is the inverse permutation of $s$. It returned a 3D view of the passed array.Convert 1D numpy array to a 2D numpy array along the column. The m × m permutation matrix P ( pij) obtained by permuting the columns of the identity matrix Im, that is, for each i, pij 1 if j ( i) and pij 0 otherwise, will be referred to as the column representation in this article.
