# cpp_computeAFFMean: Compute the AFF mean of a vector In ffstream: Forgetting Factor Methods for Change Detection in Streaming Data

## Description

Given a vector x and a value eta for step size in the stochastic gradient descent for the adaptive forgetting factor, this returns the value of the fixed forgetting factor mean \bar{x}_{N, \overrightarrow{λ} }, where N is the length of x. Algorithm is implemented in C++.

## Usage

 1 cpp_computeAFFMean(x, eta) 

## Arguments

 x Vector of numeric values values. eta Value for the step size in the gradient descent step.
