MCD-RoSIS – A robust procedure for variable selection

Abstract: Consider the task of estimating a regression function for describing the relationship between a response and a vector of p predictors. Often only a small subset of all given candidate predictors actually effects the response, while the rest might inhibit the analysis. Procedures for variable selection aim to identify the true predictors. A method for variable selection when the dimension p of the regressor space is much larger than the sample size n is SIS -Sure Independence Screening -recently proposed by Fan… Show more

“…Winter cereals reach a considerable rooting depth in the initial phase and a possible final rooting depth of more than one meter. Thus, the accessibility of deeper soil layers guarantees yield stability even in regions with low rainfall (annual precipitation lower than 600 mm) [Guddat et al, 2015]. To better understand the spatial variability within the SMOS L4 pixel, Sentinel-2 NDVI images at 10 m are shown in Figure 4.4a-d for the four in-situ stations, respectively.…”
