Normally two approaches are used for valuing a real estate property: income and sales comparison. The sales assessment approach values a real estate property based on sale prices of similar properties. In this case the properties with familiar individuality are basically on the same price level, it would be typical to use a linear regression model to complete this demonstration. Our team will examine the significance of numerous independent variables to a real estate value. Two important strategies to regression testing is to run all test, and run a subset of the test based on a prioritization system.

3.Size of the home in square feet
5.Distance from the center of the city in miles
7.Garage attached
8.Number of bathrooms

The graphic figures of stable variables are listed in the table. The team observes cost and dimension have larger scales, which leads us to believe the logarithm of two variables is weak. The team can detect weak linear association among some pairs. Though, this start examination is not adequate enough to sense the significance of descriptive variables to the house cost. When using OLS to estimate a linear regression model with all eight descriptive variables. Regression analysis is used for prediction purposes. A regression model is a statistical model that is used to predict the values of a dependent or...
