envoutliers

Three semi-parametric methods for detection of outliers in environmental data based on kernel regression and subsequent analysis of smoothing residuals. The first method (Campulova, Michalek, Mikuska and Bokal (2018) doi:10.1002/cem.2997) analyzes the residuals using changepoint analysis, the second method is based on control charts (Campulova, Veselik and Michalek (2017) doi:10.1016/j.apr.2017.01.004) and the third method (Holesovsky, Campulova and Michalek (2018) doi:10.1016/j.apr.2017.06.005) analyzes the residuals using extreme value theory (Holesovsky, Campulova and Michalek (2018) doi:10.1016/j.apr.2017.06.005).
