coef function

Extract coefficients from an averaging model

Function to extract fit model coefficients from an object returned by rav.

coef(object, ...)

Arguments

• object: An object of class rav containing an estimated averaging model.
• ...: Optionally more fitted model objects.

Details

Returns the parameters of an averaging model fitted by the rav function, in the order: s0, w0, s(k,j), and w(k,j).

As default, the function extract the cofficients of the (first) best model. The optional argument whichModel can be specified to extract the values of another model. Options are:

1. "null": null model
2. "ESM": equal scale values model
3. "SAM": simple averaging model
4. "EAM": equal-weights averaging model
5. "DAM": differential-weight averaging model
6. "IC": information criteria model

Returns

A numeric vector.
