when using variable indicator in regression model, when is the constant and the continuous variables correlated? what variable can be used to specify a pattern in a regressor model how to construct a causal model which variable in a causal model must be considered independent variable? what is the dummy lag in a linear regression model can a dummy predict a dummy variable how to use indicator variables in r model can a continuous variable be a predictor of demand which continuous variable is a lag indicator how do you do causal analysis how to use variables in regression analysis and dummies what is a dummy variable used for in a causal regression can you use multiple continuous variables to calculate demand which continuous variable has a dummy trap how do you create a dummy for each continuous variable in your regression model how to use continuous variable r when using multiple continuous variables in r, what is the risk of a dummy variable trap which type of variables can trigger a dummy model is it normal to use an exogenous regressor in r which variables can be used as covariances in calculating regressions
