Title:
 Evaluation of methods for the detection of spatial outliers in the yield data of winter wheat

Language: English

Summary:
This work presents evaluation of three methods of spatial outlier detection in yield data. Raw yield data used for the analyses came from a field cropped with winter wheat in 2009 located in north of Poland. Three methods were used for the spatial outliers detection, one method based on histogram and two methods based on spatial autocorrelation coefficient (Moran’s I). Different percentages of the outliers were detected using each of the methods and quite weak correspondence between the methods was achieved.
