In 4 4, we looked at using temperature (celsius) as a 2nd independent variable (x2) in order to improve our prediction of halloween visitors. In 4 5, we are going to use the 2nd x in a different improve our prediction of halloween visitors way, but the goal is still to. Case 4 5 a curvilinear (allowing the line to bend) In a simple regression, a straight line is used to describe the relationship b/w 2 variables (halloween + visitors: [pictorial] In some situations, however, a better description might be obtained by allowing the line to curve a curvilinear regression line has the form: often a linear component (angled a little bit); like an tilted upside down. 2 x columns; squaring the scores that one has: ssp table. Using this values, the slope of a simple regression is calculated to be 3. 18 and the constant is calculated to be 52. 24: that is, the simple regression line is.
