Question about low noise figure

As the equation (14) in the above link , the noise In can be separated to Inu and Inc ,and Inc is correlated to Vn theoretically. My question is how to get the correlation between Inc and Vn in practice? Is it possible to measure the Yc [equation (15)] realistically? Or how can we get the optimum reflection coefficient realistically?

Optimum Source Reflection Coefficient is defined in two ways.
-Modeling ( less accurate )
-Measurement ( more accurate )
Because Noise ( voltage or current) is NOT deterministic signal, instead it's a Random Process.Therefore calculation of those variables is just theoretical
approximations.
