Hi all,
Is it possible to draw line segments in a 3d space plot?
I'm interested to draw the errors from an observed value to the regression plane, for a textbook example in an Intro Stats handbook for multiple regression.
I used the scatterplot3d package to draw the regression plane.
An example on how to draw segments for residuals on a regression plane with scatterplot3d is shown in Section 4.2.2 (pp. 20-22) of
Ligges, U. and M�chler, M. (2002): Scatterplot3d - an R Package for Visualizing Multivariate Data. Technical Report 22/2002. SFB 475, Department of Statistics, University of Dortmund, Germany.
