I am taking an e-learning course, Applied Analytics Using SAS Enterprise Miner. I am getting a result for a practice in the regression model lesson different from the solusion. I followed the steps and still not getting the same result in the solution. The problem involves tha dataset called Organics. The practice involved is "Impute missing values, and then run the regression node." (screen 41 in the Regression Models lesson). The number of input variables should have been 16. I am getting a lot more (41). I do not what causes different answer. I followed the steps as instructed. Has anyone taken this course and experienced the same problem? I need to resolve this issue before I can move on as the practices in later lessons depends on the answers in previous practices.

I haven't taken e-learning in a long while, but SAS courses have the solutions for all exercises.
Courses are designed so that you can move on even if you miss something. Try to locate the solutions, ideally as an XML that you can import.
Do you have the contact for an instructor on the e-learning?

Thank you for your response. The solution is part of the course. I am not getting different result. The course is a self-paced e-learning format and there is no instructor associated.

I am still stuck with the problem. I am not getting the same result. I was looking for someone who took the same course and wanted to know how they resolved the problem. I cannot not move forward as the next exercise use the output data from the exercise I am having problem with. I seeked the help from the SAS tech support. They said they only assist with software installation.

I think i may help you ... i am familiar with this course.
But from your description ... i do not know what is your problem and in which part exactly. more details please?
And did you followed the steps in chapter three to prepare the data before jump to four directly, because it depends.
Where is the difference you get from the material in the data set itself or the imputation or the regression?

Mohamed has asked some good questions. Providing your results that differ from the course's results will help us identify the problem.

Robert / Mohamed,
I prepared a document that inclues the steps and my result. I tried to attach the document and the site would not allow it to upload. I tried MS word, PDF, and rtf formats. None of them are working. Is there a special method for uploading a file to this site? The document contains some graphics.
