LightResponseCurveFitter_optimLRCBounds {REddyProc}

LightResponseCurveFitter optimLRCBounds

Description

Optimize parameters with refitting with some fixed parameters if outside bounds

Usage

LightResponseCurveFitter_optimLRCBounds(theta0, 
    parameterPrior, ..., dsDay, lastGoodParameters, 
    ctrl)

Arguments

theta0

initial parameter estimate

parameterPrior

prior estimate of model parameters

...

further parameters to .optimLRC,

dsDay

argument to .optimLRC, here checked for occurrence of high VPD

lastGoodParameters

parameters vector of last successful fit

ctrl

list of further controls, such as isNeglectVPDEffect = TRUE

Details

If parameters alpha or k are outside bounds (Table A1 in Lasslop 2010), refit with some parameters fixed to values from fit of previous window.

No parameters are reported if alpha<0 or RRef < 0 or beta0 < 0 or beta0 > 250

Not parameters are reported if the data did not contain records that are near light saturation. This is checked by comparing the prediction at highest PAR with the beta parameter

Value

list result of optimization as of LightResponseCurveFitter_optimLRCOnAdjustedPrior with entries

theta

numeric parameter vector that includes the fixed components

iOpt

integer vector of indices of the vector that have been optimized

convergence

scalar integer indicating bad conditions on fitting (see LightResponseCurveFitter_fitLRC)
