A function links an input value to an output value. The inverse of a function is a function that links the output value back to the input value. The inverse function for \(f(x)\) is written as \(f ...

Any function and its inverse are symmetrical about the line\(y = x\).

The sample inverse autocorrelation function (SIACF) plays much the same role in ARIMA modeling as the sample partial autocorrelation function (SPACF) but generally indicates subset and seasonal ...
