Summation of Study Subgraph - Periodic

This study calculates and displays a periodic Summation of the data specified by the Study and Subgraph to Reference Input.

Let \(X\) be a random variable denoting the data from the Study and Subgraph to Reference, and let \(X_i\) be the value of the of this data at Index \(i\). Let the Length Input be denoted as \(n\). Then we denote the Summation - Periodic at Index \(t\) for the given Input as \(\mathrm{sum}_t(X,n)\), and we compute it for \(t \geq n - 1\) as follows.

\(\displaystyle{\mathrm{sum}_t(X,n) = \sum_{i = t - n + 1}^tX_i}\)

For an explanation of the Sigma (\(\Sigma\)) notation for summation, refer to our description here.
