Each record in the data file has the following layout:
Variable(1) Variable(2) . . . . . . . Variable(k)
The records must be sorted by: by-variables, independent variable.
File Contains Column Headers
Joinpoint can process data files where the first record contains the names of each variable in the data file. The names should be delimited with the same field delimiter used in the rest of the file. If the first record in your data file contains the variable names, please check the "File contains column headers" checkbox. Once this is checked, the data grid on the Input File tab will be updated accordingly.
Field Delimiters
The variables may be separated by a single character. This field delimiter may be a tab, space, comma, or semi-colon.
Missing Characters
Missing values may be represented by a space, a period, or the text string NA.
