Explanation:
Regression coefficients represent the relationship between the independent and dependent variables in a regression model. When the regression coefficients are zero, it means that there is no relationship between the independent and dependent variables.
Reasons for zero regression coefficients:
- Perfect multicollinearity: When there is perfect multicollinearity among the independent variables, the regression coefficients can be zero. This means that one independent variable can be perfectly predicted by a combination of other independent variables.
- Orthogonality: If the independent variables are orthogonal to the dependent variable, the regression coefficients can be zero. This implies that the independent variables do not have any impact on the dependent variable.
- Incorrect model specification: Zero regression coefficients can also occur if the model is misspecified and the independent variables are not relevant in explaining the variation in the dependent variable.
Conclusion:
In conclusion, when the regression coefficients are zero, it indicates that there is no relationship between the independent and dependent variables in the regression model. This could be due to perfect multicollinearity, orthogonality, or incorrect model specification.
