Every time I look at SAS's result page I get lost among the numbers. Is there any online material that can help with understanding SAS's result page?
The best place to look for understanding SAS procedures is the online documentation at the SAS support page.
For the output of a particular procedure, there is a "Displayed Output" page within the "Details" section which describes most of the output. For example, here's the "Displayed Output" page for
You can also look through the examples the documentation provides in the "Examples" section. Using
proc glm again, here is a list of examples in which the syntax and output are described pretty well.
To gain some more context, also read a statistics text book that describes your analysis technique of choice. Try to link the theory you are reading to the output you see on the screen. Make this kind of link already helps you to understand what you are reading in the book. For example, for a simple linear regression common outputs are the significance of the coefficients and the R². Good luck!
