The general form of its probability density function is. The parameter is the mean or expectation of the distribution (and also its median and mode ), while ...
Hace 22 horas · A hypergeometric series is formally defined as a power series. in which the ratio of successive coefficients is a rational function of n. That is, where A ( n) and B ( n) are polynomials in n . For example, in the case of the series for the exponential function , we have: So this satisfies the definition with A(n) = 1 and B(n) = n + 1 .
Hace 22 horas · In mathematics, the determinant is a scalar value that is a certain function of the entries of a square matrix. The determinant of a matrix A is commonly denoted det (A), det A, or |A|. Its value characterizes some properties of the matrix and the linear map represented, on a given basis, by the matrix. In particular, the determinant is nonzero ...
