xy0_SK_EBLUP_LME.f {TapeR}

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
