TC descriptive model.

The first two columns list each environmental variable and the associated lag with the strongest Spearman correlation to log10-transformed EC concentration. daytime and hours_from_noon were excluded from the temporal lag process. chl and turb values were log10-transformed and all variables were normalized (i.e. made unitless) prior to model fitting. The Concentration Model columns show the variable coefficients and associated p-values of the generalized least squares regression model; values where p-value is less than 0.05 are bolded and variables with no value were removed from the model due to high variance inflation factor (VIF). Note than because TC was never measured below the LOD, no Binary Model (i.e. random forest) was fit.
