Then why do you think of model which has insignificant variables and high coefficient of detemination at the same time? ... View more

It's ok, I've got it done already. Thx alot for explaining patiently 🙂   But if you don't mind to help me one more time.. I did the regression analysis. I know that generally, the value of coefficient determination will become higher as we add more variables into the model. But the problem is, eventhough the coefficient determination is high as much as 99%, I got some variables insignificant, even at alpha 10%. Do you know what's the reason it may possibly happen?   ...

But if I have all the value of x variables untill 2019, I will have different value of parameters for the best fit models, right? how about that... ... View more

I have the time variable which I named it as "Waktu". If that so, I still can have the forecast from the proc reg? Because, actually I use the regression analysis on my time series data to analyze holiday and trading day variation. So I got the regression model as its best fit and want to do the forecast for at least a year. ... View more
