Phase-typing as a predictor of light-treatment response was proposed by Lewy and colleagues [ 33] and has been previously employed to select light treatment timing prospectively [ 34].
Most important, correlations of AOD and PM2.5 may reflect variability in PM2.5 that could be predicted by other sources of information, such as land use or meteorology or estimation of large-scale regional variation through spatial smoothing of monitored values, so they may overstate the usefulness of AOD as a predictor in light of other readily available information.
Stand variables that heavily weighted the influence of larger trees on light attenuation were weak predictors of understorey light at the micro-site scale.
Vertical sighting tube estimates of canopy cover (R2 = 0.73), light estimates derived from hemispherical photography (R2 = 0.70), and spherical densiometer estimates of canopy closure (R2 = 0.68) were the best single predictors of understory light transmittance.
Genetic and clinical predictors of EXERCISE, LIGHT and MODERATE responders and nonresponders were tested using binary logistic regression models.
A regression analysis was run using the primary axis (the 'LES') as the predictor of species' whole-plant light compensation point (WPLCP) taken from Baltzer and Thomas [19].
Furthermore, as was the case for the Sepilok dataset, the first component was a significant predictor of available measures of juvenile light requirements for each site.
Tenure was found to be a significant predictor of the reasons for call lights being meaningful.
The respondent's primary working shift was also a significant predictor of the reasons for call lights being meaningful.
Both studies therefore agree that instantaneous measurements of light interception can be very useful predictors, as long as they are obtained during a critical time when light becomes limiting for plant growth [27].
Several predictors of response to light treatment in winter depressives have been identified: the ratio of atypical to classical symptoms of depression [ 15] and hypersomnia, increased eating and younger age [ 16].
