Please Note That
- The first column and first row are removed by the library before processing, in attempt to remove indices and headers. So the csv MUST follow the format as shown in sample.csv shown in the Example section.
- The input data file MUST contain three or more columns.
- The second to last columns of the data file MUST contain NUMERIC values.
- The number of weights, impacts and columns (second to last) MUST be SAME.
- Impacts MUST either be '+' or '-'.
- Impacts and Weights MUST be separated by , (comma).
