I have Y, X1, X2 and X3 columns in Origin7 and want to do multiple regression to get an explicit equation. I highlighted X1,X2,X3 columns and then select "statistics-->multiple regression", but the error message occured with "Error! You must select one to nine columns.". I have no idea now. Any help from you would be very appreciated! Thanks in advance!
We tried this from v6.1 onwards to the latest version and it works fine for us. How is your worksheet organized? Are there other columns than the four you mentioned? Perhaps you could send your OPJ to tech support if the problem persists?
