For the attached data, find the multiple linear regression formula using X1 as the dependent variable and X2-X7 as the independent variables.
Using whatever means necessary find the model of best fit and justify your choices.
Determine what variables are significant at a sig. level of 10%.
State what independent variable if any should be tested for interaction.
Choose any two observed variables and calculate their residuals.
What are the 4 assumptions about the error terms, (residuals) that need to be in order to perform multiple linear regression.
