Prediction diameter (no variances) for given tree and TapeR-object using BSpline Matrix all in C++
lmeSKEBLUP(xm, ym, xp, par, RV)
a list holding several elements, perspectively only the estimated diameter
relative height of measured diameter
measured diameter for calibration
relative height for which diameter prediction is required
a TapeR-object (including padded knots vector)
numeric vector holding assumed residual variance for each observation
code implementation in C++ following the code base of TapeR. Bspline matrix code taken from R-package splines to avoid the need of calling R from C.
