To analyze multiple tax filers, the user creates a csv file with the filers' data. Each row of the csv file represents a filer and each column represents a variable. Please note that the file should not have column headings and the year must be the same for all observations. The input file should have 28 columns in the following order:
- RECID (ID for tax filer)
- year
- mstat (1 - single; 2 - married)
- page (age of primary taxpayer)
- sage (age of spouse)
- dep13 (number of children under 13)
- dep17 (number of children from 13 to 16)
- dep18 (number of children from 17 to 18 AND from 19 to 24 and a full-time student)
- otherdep (other dependents)
- pwages (wage of primary taxpayer)
- swages (wage of spouse)
- dividends (dividend income)
- intrec (interest received)
