R users: This is more of a general question.
I am trying to conduct hypothesis testing about the difference of two angles extending from the same point. I am reading directional statistics by Mardia, but it seems to talk about only frequency distribution on the circumference drawn by the unit length vector. My problem involves the weighted mean direction. Weighted by which I mean is that the unit vectors are weighted by the frequencies attached to the census zones. Have anyone known good textbooks and R packages to do directional statistics? Thank you very much Taka _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
