Test different models to determine which model you should use to compute the information Ultimate Realty needs. That is, consider the differences in the sum-of-squares-error values, frequency plots to check normality, scatter plots to check linearity, etc. From the choices below select which model you have found is best overall.

-All the models tested will provide the same accuracy and quality of results

-Simple linear

-Multivariable quadratic

-None of the models tested will provide results

-Multivariable log-quadratic

-Multivariable log-linear

-Simple quadratic (non-linear, polynomial)

-Simple log-quadratic

-Simple log-linear (non-linear, logarithmic)

-Multivariable linear
