F.update.df {mra} | R Documentation |
Updates the degrees of freedom in a fitted object to either the value estimated from the rank of the variance-covariance matrix, the number of coefficients, or a user-specified value.
F.update.df(fit, df=NA)
fit |
An MRA fitted CJS model. Class must be c("cjs", "cr"). These are produced by |
df |
The new value for degrees of freedom.
If |
An object (list) of class c("cjs","cr") with degrees of freedom, AIC, QAIC, AICc, and QAICc updated.
