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.
An MRA fitted CJS model. Class must be c("cjs", "cr"). These are produced by
The new value for degrees of freedom.
An object (list) of class c("cjs","cr") with degrees of freedom, AIC, QAIC, AICc, and QAICc updated.
