Notation for a Function Applied to a Sequence of Average Vectors (s(yˉ1yˉk)s(\bar{\mathbf{y}}_1 \dots \bar{\mathbf{y}}_k))

The notation s(yˉ1yˉk)s(\bar{\mathbf{y}}_1 \dots \bar{\mathbf{y}}_k) represents a function, denoted by ss, that takes a sequence of kk vectors, from yˉ1\bar{\mathbf{y}}_1 to yˉk\bar{\mathbf{y}}_k, as its input. The bar over each bolded variable yi\mathbf{y}_i indicates that it is an average vector.
