The Data Grid provides users with a snapshot of their data file and shows them how Joinpoint will parse the file.
Once a user selects their input data file, the Data Grid will be populated with the contents of the file. The contents of the grid are updated whenever the user adjusts the Delimiters, Missing Character, or File Contains Column Headers controls.
Users should use the Delimiters, Missing Character, and File Contains Column Headers controls until their data is correctly displayed in the Data Grid. Once the appropriate settings have been made, then users can go and set the other variables (independent, dependent, and by) and controls on the tab.
Users can select to display only a set number of records from their input file. The choices to display the following number of lines: 5, 10, 20, 50, or 100.
When users set the independent, dependent, heteroscedastic/correlated errors options, and by-variables, the header row in the data grid will label which data column was assigned to which variable. The user will be alerted if there is a conflict in the selected variables.
