ARMA(p,q) prediction with pre-determined coefficients
...100 values.
And most importantly,I have also calculated the coefficients in some way
(these I want to use for prediction).
How can I use R to predict the value of Loss_22 (say) because I cannot
manually input the values of the white noise error at time 21 (since I
don't know what the actual observationL_21 is going to be).
I guess the arima() function can be used for this purpose and was going
through it where I found : "When regressors are specified, they are
orthogonalized prior to fitting unless any of the coefficients is fixed ".
I wanted to know exactly how to fix the coefficients to...
