why do ols estimates involve taking vertical deviations of the points to the line rather than horizontal distances? why do we use vertical distances why do ols estimation involve taking vertical deviation of points to the line rather than horizontal distances? which of the following describes horizontal distance? why do ols estimates involve taking vertical deviations of points to the lines rather than horizontal distances? why does ols include taking vertical deviations of points to the line rather than horizontal distances? why use vertical deviations why are vertical distances useful why are horizontal distances a variable? why vertical deviation why does ols estimation involve taking vertical deviations of the points to the line rather than horizontal distances? why vertical deviations what is the purpose of the vertical deviation what is the purpose of vertical distance why do horizontal and vertical distances differ at different ols why is ols used why do ols models involve taking vertical deviations of points to the line rather than horizontal distances? why use vertical distances what is the purpose of vertical distances what does vertical deviation in ols estimation mean
