cdfLogistic ============================================== Purpose ---------------- Computes the cumulative distribution function for the logistic distribution. Format ---------------- .. function:: p = cdfLogistic(x, loc, scale) :param x: Values at which to evaluate the cumulative distribution function for the logistic distribution. :type x: NxK matrix, Nx1 vector or scalar. :param loc: Location parameter, ExE conformable with *x*. :type loc: NxK matrix, Nx1 vector or scalar :param scale: Scale parameter; ExE conformable with *x*. :math:0 < scale. :type scale: NxK matrix, Nx1 vector or scalar :return p: Each element in *p* is the cumulative distribution function for the logistic distribution evaluated at the corresponding element in *x*. :rtype p: NxK matrix, Nx1 vector or scalar Examples -------- :: // Values of interest x = { 1, 2, 3 }; // Location parameter loc = 0; // Scale parameter s = 2; p = cdfLogistic(x, loc, s); After the above code, p will equal: :: 0.6225 0.7311 0.8176 Remarks ------- The cumulative distribution function for the logistic distribution is defined as: .. math:: f(x, \mu, \sigma) = \frac{1}{1 + exp(-z)} where .. math:: z = \frac{x - \mu}{\sigma} .. seealso:: :func:pdfLogistic
