We derived theoretical formulas for the variance of extreme learning machine ensemble in a general case of a heteroskedastic noise. They provide a decomposition of the variance, which helps in the understanding of how the different sources of randomness contribute. The application of the proposed method to simulated datasets shows the effectiveness of the newly introduced estimations in replicating the expected variance behaviours.
