Then, AT is by de nition an n m matrix, and therefore TAT is n m as well. Since A = A , the dimensions of AT must be the same as the dimensions of A. Therefore, m n must be the same as n m, and so we can conclude that m = n. This means that A is n n, which means that A is a square matrix.

The F-critical value is a specific value to which your F-value is compared. You can reject the null hypothesis if your calculated F-value in a test is greater than your F-critical value. In an F-Test, however, the statistic is only one measure of significance. harley johnsonWebSuppose f : A !B and g : B !C are functions. (a) Show that if g f is injective then f is injective.
