Internal functions for predict.fitmodel function.

Internal functions used for prediction. EstChat: estimates concentration. BlockSigma: estimates the variance-covariance matrix. CalcSE: calls on C code to calculate the standard error. ConvertFacts: Internal function that determines the conversion constant to use for loads and flow.Conversion to Million tonnes: C = mg/L Q = m^3/s (K.loads) mg/l x m3/1000 = 1kg & 1kg = 0.001 t Conversion to millions of ML (K.flow). EstLoadYS: Function used in predict.fitmodel to estimate the load based on predicted concentrations from predicted hourly flow records. EstLoad: Function called by EstLoadYS ExtractDailyLoads: extracts the daily loads. Intervals: calculates confidence intervals.
