January 11, 2018 Correlated noise analysis with Gaussian Processes Elyar Sedaghati As precision of observations improves with improved instrumentation, our observations are becoming more and more dominated by the correlated to red noise. Incorrect treatment of their presence will lead to biases in both the accuracy and the precision of derived parameters. Increasingly, the preferred method of their treatment is using Gaussian Processes or GPs. This is because they provide a stochastic, non-parametric approach to the treatment of the systematic noise and have been shown to provide more realistic estimates of parameter uncertainties as well as more accurate solutions. Through the use of some dummy data, I will show how the ignorance of red-noise analysis leads to errors and present some basic ideas behind implementing GP’s
