Regression error: AFx Library library exception: Error 106: Argument 1 must be a positive definite matrix. RRS feed

  • Question

  • I have a simple 4-step pipeline setup.

    I'm importing my CSV file, doing cross validation with linear regression, and then evaluating the result.

    The first two steps pass, but when it tries to run the model it fails with this error:

    AFx Library library exception: Error 106: Argument 1 must be a positive definite matrix. 

    I have no idea what this means, or why it's happening.  I do have some null values in my data file - is that the issue?

    thanks
