linearity in the relationship between a dependent variable and a set of independent variables
Homework Answers
Regression analysis (also known as predictive analytics) attempts to establish:
a mathematical relationship between a dependent variable, for which future values will be forecast, and one or more independent variables with known values.
because:
1) multicollinearity: it is an assumption of regression
2) linearity in the relationship between independent variables: the linear relationship will be between the independent and dependent variable if we are doing linear regression.
3) multiobjective: property of regression.
4) linearity in the relationship between a dependent variable and a set of independent variables:
it is true only for linear regression. if it is quadratic or logistic regression then it is not true.
