Hello! First, thank you Sven for uploading this function. For some data I get the following message which I can't interpret adequately: ----output start---- BreitungCandelonTest(emplrate,capacity,conditioning,lagorder,points,siglevel \ ) Date strings inconsistent error in new starting obs error in function BreitungCandelonTest Error executing script: halting BreitungCandelonTest(emplrate,capacity,conditioning,lagorder,points,siglevel) ----output end---- What's the problem here? Artur
