Explain why two perfectly multicollinear regressors cannot be included in a linear multiple regression. If those same two regressors were not perfectly collinear but highly collinear what difference, or differences, would that make? Give an example of a pair of perfectly multicollinear regressors.
MULTICOLLINEAR REGRESSION:
LINEAR MULTIPLE REGRESSION:
((THE MAIN FACTOR IS THAT IN MULTICOLLINEAR REGRESSION WE USE independent variable BUT IN LINEAR REGRESSION WE USE depenednt variable.
THEN LINEAR EXPRESSION HAD scalar response,MULTICOLLINEAR REGRESSION HAD variable response.))
EXAMPLE FOR MULTICOLLINEAR REGRESSION:
THIS WILL BE OCCUR IN WHERE HIGH CORRELATIONS OCCUR.
The casual example is :A Person's height and weight.
female and male equalities.
performaces between many students.
SO THESE ARE SOME OF THE EXAMLES OF MULTICOLLINEAR REGRESSION.
