Hello. Does somebody happen to know whether ARIMAX method can have three variables input? Because I've never known if there's ARIMAX with more than one variable input. Please help, thank you so much.

understood. thankyou so much!

Honestly I wanted to estimate the parameter in regression analysis with maximum likelihood estimation and I thought the proc genmod would do so. But now I think I was wrong?

Hi, I need to get the coefficient determination value from the proc genmod. I've read the manuals on SAS about this proc but I could not find the statement. Is that mean this proc can not produce the value of coefficient determination? Thanks before.

sasgiaz · ‎03-22-2019

how about the coefficent determination? do you know the syntax to get the value?

Hi, I cannot get the residuals from this syntax, I dont know maybe something wrong with this. proc genmod data = acc; model y = x1 x2 x3 x4 x5 x6 Mt/dist=normal link=identity noint; output out = Residuals; run; Does somebody know how to get the residuals from the model? thankyou

Hi, I'm sorry for the late respond. It's ok i'm done with the anaysis. Thank you so much for your kind help and attention:)

Hello I'm sorry for the late respond but I'm so thankful for your kind help and answer. Thankyou!

so you suggest to apply another model instead of regression? what model do you think will fit?

Here's the plot Y (Bill) vs DL1, DL2, and DL3. How can I tell about the outliers? Here's the output for multicollinerity check. The dummy variables don't have high correlation. Lastly, I dont know which one is the influence diagnostics..

sasgiaz · ‎03-11-2019

Here's the plot for each DL. If the outliers should be checked I think it's obvious for each DL to have extreme value because most of the variables valued zero since it is dummy variables

sasgiaz · ‎03-11-2019

all DL is dummy variables...it contains so much zeros and some dummy proportions...it's a dummy variables for holiday variation. The VIF is fine..

sasgiaz · ‎03-11-2019

What do you think I should do?..

sasgiaz · ‎03-11-2019

Here's the syntax I use for the analysis. proc reg data = armaxvlp; model Bill = Waktu DL1 DL2 DL3/influence; run;

Hello again.. I have an unusual parameter estimation for my variable. Here's the output from SAS. Does somebody know why is the estimation of parameter for variable DL3 is very high and so different from DL1 and DL2? The interpretation of the model feels so wrong when the value is that high, because the value of DL3 shoud be around the value of DL1 and DL2. Thankyou.
