I am trying to read in a variance-covariance matrix written out by LISREL in the following format in a plain text, whitespace separated file:
Inspired by Real-world examples of co- and contravariance in Scala I thought a better question would be:
For me one of the more confusing aspects of the Scala type system is understanding covariance, contravariance, type bounds etc.
