A decentred predictor for circular-circular regression
圆周对圆周回归中的偏心预测器
This paper considers the prediction of a y-angle, given an x-angle in a circular-circular regression. The predictor under study is a rotation of the decentred x-angle, denned as the direction of the sum of the unit vector corresponding to angle x plus a decentring vector. The parameters are defined as those which maximise the average residual cosine. This predictor is shown to perform well when the data come from a bivariate von Mises distribution or from a wrapped bivariate…
