Hello, I have a question, how can I predict using proc panel.
Let's take an example : http://support.sas.com/documentation/cdl/en/etsug/63939/HTML/default/viewer.htm#etsug_panel_sect049....
The data years are : 1970–1984
In this example, you run the next code:
proc panel data=airline;
id i t;
model lC = lQ lPF LF / fixone;
run;
The output you got was :

Now the question. How can I predict Total cost for years 1985 - 1988.
Can I use parameters?
