发帖数: 38 | 1 I'd like to know the agreement of 1st rating and 2nd rating.
the p value of McNemar's Test is 0.0455, but the Kappa is 0.6602.
How should I explain? Thanks.
Kappa is 0.66. Does that mean moderate agreement? Should I only use kappa in stead of McNemar's Test to explain agreement? Thanks.

发帖数: 38 | 2 McNemar's null hypothesis is
The null hypothesis of marginal homogeneity states that the two marginal
probabilities for each outcome are the same
for one variable: p value of McNemar's=0.2, which means the two ratings are
the same. But the kappa is 0.1966, which is poor agreement.
Isn't this conflict?
Hope someone can help me with this. |
