Third order polynomial cubic
WebApr 7, 2024 · Regarding the model, I chose poly (x,3) because the model with "poly (x, 2)" was not significant, while the model with only the lower term was. I read that a third-order term easily allows the model to bend down after the peak. Also, the value of R2 doubled from the first to the third-order model, and a likelihood test showed that the more ... WebWhile solving a problem a friend said - this polynomial is 3rd order ( ax3 + bx2 + cx + d ), with {a, b, c, d} real coefficients, so it must have a real root. I didn't want to sound stupid and I …
