Measures of agreement
...that for each document, each measure (there
are 9) has three variables: ap_(measure), nb_(measure), and
knn_(measure). ap is me (Andrew Perrin), nb is Naive Bayes, and knn is
knn.
I have two questions:
1.) I have used the code in the Using R for Psychology... paper to
calculate Cohen's Kappa (kappaFor2). It returns a (fairly low) kappa, but
also some warnings I don't understand:
> kappaFor2(ap.nb.df$ap.sub,ap.nb.df$nb.sub)
kappa S.E. z.stat p.value
0.09411765 0.33707660 0.27921738 0.78007800
