Estimated that the average value of Y changes by bi for each 1 unit increase in Xi holding all other variables constant (ceterus paribus).Interpretation of Estimated Coefficients For each increase in one inch of insulation, the estimated average use of heating oil is decreased by 20.012 gallons, holding temperature constant. Sample Multiple Regression Equation: Example Excel Output For each degree increase in temperature, the estimated average amount of heating oil used is decreased by 5.437 gallons, holding insulation constant. EXCEL spreadsheet for the heating oil example.PHStat | Regression | Multiple Regression ….

Multiple Regression Model: Example (0F) Develop a model for estimating heating oil used for a single family home in the month of January based on average temperature and amount of insulation in inches. Multiple Linear Regression Equation Too complicated by hand! Ouch!
