Calculate Akaike weights for model averaging

+ + +
+ +
+

Akaike weights are calculated based on the relative +expected Kullback-Leibler information as specified +by Burnham and Anderson (2004).

+

aw(object, ...)
+
+# S3 method for mkinfit
+aw(object, ...)
+
+# S3 method for mmkin
+aw(object, ...)
+ +

Arguments

+ + + + + + + + + + +
object

An mmkin column object, containing two or more +mkinfit models that have been fitted to the same data, +or an mkinfit object. In the latter case, further mkinfit +objects fitted to the same data should be specified +as dots arguments.

...

Not used in the method for mmkin column objects, +further mkinfit objects in the method for mkinfit objects.
