what makes a model stationary when do dependent and independent variables become stationary what is the constant term in a time series what makes a model constant term how to calculate constant term of dependent variables which variable should be a constant in a time series if a variable is dependent what term will it be lost in differentiation process? what is the constant term of time series? when do independent variable get constant term in time series is time series dependent and independent variables when does constant term become fixed? why is the constant term a variable why is constant term an important variable in econometric model is the dependent variable stationary when the independent and dependent variables change in a model why why constant term is not fixed can time series be fixed in time series how variable is dependent variable why is it important to have a constant term in the time series? which variable can be estimated with constant term
