The example above is fixed time, a snapshot in time. To denote a time series analysis, the subscript changes to t. OLS cannot do pooled cross-sectional and time series. Simple vs Complex or Multiple Regression. Simple linear regression has only one independent variable: Yi = Β0 + β1 Xi + εi . Multiple linear Regression has multiple ...

A simple regression, which implies a single independent variable, can accommodate most any functional relation between the left-hand side [LHS] (i.e., dependent) variable and right-hand side [RHS] (i.e., independent) variable.In general, it is easier to think about the relation between the variables as either linear or non-linear (i.e., concave, convex or some arbitrary polynomial).

Linear Regression (Definition, Examples) | How to Interpret?
A simple linear regression model appears reasonable to try to model the relationship between Y and X. Step III. Fit an initial regression model and check the assumptions of the regression model. We try a simple linear regression model. Bivariate Fit of Percentage Calls By Forecast Low Temperature. Linear Fit

Both linear and polynomial regression are susceptible to problems when predictions of Y are made outside the range of the X values used to fit the model. This is referred to as extrapolation. Least Squares Estimation (Sec. 11-2)
