hi,
I'm using the sem package, and I want to make sure I'm interpreting the output
correctly. Here is an excerpt of my output. When I report the MWD error, should
I say that 59% of the variation in MWD is not explained by the model, or that
59% of the variation is explained, or something entirely different.
