I use balance panel with 22 cross section units and 9 years. When I apply first difference method to my model, it should be 22*(9-1) = 176 observations applied to estimate the model. I use the following procedure: proc panel data= ex1; id cross time; model y= d2001 d2002 d2003 d2004 d2005 d2006 d2007 dfemale /fdone ; run; I understand that SAS use 167 observations to estimate the model (Consider from Den DF in the output below). When I use other software, it uses 176 observations as I expected and this make the SAS results different from other softwares. What wrong to my SAS code? Thank You.

Hello, I have the following data set. city Year D87 X dx 1 82 0 a - 2 87 1 b (b-a) 3 82 0 c - 4 87 1 d (d-c) 5 82 0 e - 6 87 1 f (f-e) What procedure should be used to achieve dx ? Thank You

Hello, I have the following data set. How do I sort the data based on the Capacity which is the string variable? (I want to order descending capacity) I tried the following codes, but it provide the same output: proc sort data= stats2 SORTSEQ= LINGUISTIC ; by capacity; run; Thank You.

Hello, I have two variables pref_hat and BrewingTime (2 mins, 4 mins, 6mins and 8mins). I used the following procedure: proc sgplot data = conjoint; scatter y=pref_hat x=BrewingTime; run; How can I connect the mean of pref_hat in each of BrewingTime in the scatter plot below? Bests, Golf

I also try another procedure "gplot", but it looks similar even I add option "areas=1" (picture is below). proc gplot data=chap3_binomial; plot binomialpdf*x / areas=1; Is there other procedure to get my objective? Thank you. run;

Hello, I have 2 variables: binomialpdf and X. I use the following procedure proc sgplot data =one; scatter y=binomialpdf x=x; run; Is there anyway to put area under each dot in the above graph? Thank You.
