In mathematical definition way of saying the sigmoid function take any range real number and returns the output value which falls in the range of 0 to 1. If you differentiate a multivariate expression or function f without specifying the differentiation variable, then a nested call to diff and difff,n can return different results.

The specific impulse response calculated by impulse is the dynamic multiplier, defined as the partial derivative of the output response with respect to an innovation shock at time zero for a univariate arima process, y t.
