@@ -82,7 +82,7 @@ As this value approaches 0, the resulting weights will be almost equal,
 while values closer to 1 will put greater weight on the tail elements of the vector.
 
 For example, the following call generates exponential weights for ten observations with ``λ = 0.3``.

 Simply passing the number of observations `n` is equivalent to passing in `1:n`.
