xy0_SK_EBLUP_LME.f: find relative height of given diameter

In TapeR: Flexible Tree Taper Curves Based on Semiparametric Mixed Models

find relative height of given diameter

Description

Internal function not usually called by users

Usage

xy0_SK_EBLUP_LME.f(xm, ym, y0, par.lme, Rfn = list(fn = "sig2"), ...)

Arguments

xm	relative heights for which measurements are available
ym	corresponding diameter measurements in height xm
y0	given diameter for which height is required
par.lme	Fitted model object, return of TapeR_FIT_LME.f
Rfn	list with function name to provide estimated or assumed residual variances for the given measurements, optionally parameters for such functions
...	not currently used

Details

function used to transform given diameter in volume calculation into height; c.f E_VOL_AB_HmDm_HT.f; with Rfn one can decide whether the measured diameters are forced to lie exactly on the taper curve Rfn$fn="sig2" or not Rfn$fn="zero". Other options are possible, see also SK_EBLUP_LME.f and resVar.

Value

relative height of given diameter y0
