WebLinear equations can have negative values in them! For example: x y -2 -5 -1 -3 0 -1 1 1 This set of values is linear, because every time x increases by 1, y goes up 2 so there is the same interval between each y value. This works even though there are negative numbers! ( 5 … So our change in y is negative 1. Now, in order for this to be a linear equation, the … WebApr 23, 2024 · A cubic equation will always have a higher R2 than quadratic, and so on. The second null hypothesis of curvilinear regression is that the increase in R2 is only as large as you would expect by chance. Your third option is curvilinear regression: finding an equation that produces a curved line that fits your points.
