Effects of growth rate, size, and light availability on tree survival across life stages: a demographic analysis accounting for missing values and small sample sizes

(As a logit link function was used in the analysis of covariates the general function relating the probability of survival to DBH is given by: \( {P}_{survival}=\left\{{e}^{\left(\beta 1 + \left(\left(\beta 2\ \left(DBH - \overline{DBH}\right)\right)\ {s}_{DBH}\right)\right)\ }\right\} \div \left\{1 + {e}^{\left(\beta 1 + \left(\left(\beta 2\ \left(DBH - \overline{DBH}\right)\right)\ {s}_{DBH}\right)\right)}\right\}. \)
