Fig. 2From: A practical guide to estimating the light extinction coefficient with nonlinear models—a case study on maizeSummary of the values reported in the literature for the light extinction coefficient k in maize and their corresponding statistical method used in the estimation of this coefficient: maximum likelihood estimation for a log-transformed linear model [LogTLM], and maximum likelihood estimation with the assumption of normality [MLE (normal)].
