Seth, I'm on to a new project where I am analyzing text and there is a numeric value that rate's that texts overall relavency to a peticular subject on a scale from 1-100.  In your humble opinion what would be the best method to analyze the text and predict the value for future postings?  It is limited to 255 charaters.   Right now I am using the linear regression model but wanted to get your opinion on text analysis. 

Also I keep running into an unstable matrix on the inverse operation.  Is this because the sample data is to small?

Have you seen the StringFeature attribute?

Uh oh! Why are you computing the inverse? What is the error message? 

I am using Gauss-Jordan elimination with partial pivoting (which can become unstable with certain matrices)
