Why would Mplus give me the message: *** ERROR The number of observations is 0. Check your data and format statement. Data file: healthOct3.dat *** ERROR Invalid symbol in data file: "1" at record #: 1, field #: 1
It does this on every file that I try to input. I double check and all files are tab delimited, have no labels in the first row, and no strange symbols such as indicated in the error message above?
Please open the data set in the Mplus Windows Editor where you can see the symbol, delete the invalid symbol which you will see as the first entry in the data set, and save the data. This is related to a problem with a new version of SPSS.
