I got an error on this data set when using:
Or using Linear Discriminant Analysis Compute node
Error is : cannot invert the inter-class scatter matrix as it is singular. Most Likely, two input columns are linearly dependent, ie. differ only by a constant factor.
as the error message states, you probably have some linearly dependent input columns. You can remove those input columns using the Linear Correlation node and the Linear Correlation Filter node.
I hope that helps. Let me know if you have further questions.
