Candidate models used in multiple regression modeling to predict average daily water temperature in the Current and Jack’s Fork Rivers, Missouri.

The variable AirTemp represents a five-day weighted moving average air temperature. The variable Season represents a value based on climate normal air temperatures, and the variable SIF (spatial influence factor) represents a spatial variation in water temperature caused by groundwater and other factors. β0 represents intercept and β1 represents slope. Akaike Information Criterion (AIC) values and model weights (wi) are displayed for each candidate model.Candidate models used in multiple regression modeling to predict average daily water temperature in the Current and Jack’s Fork Rivers, Missouri.
