Web20 Oct 2024 · Yes, polynomials are also problematic in interpolation, because of overfitting and high variability. Here is an example. Assume your dependent variable y is uniformly distributed on the interval [ 0, 1]. You also have a "predictor" variable x, also uniformly distributed on the interval [ 0, 1]. However, there is no relationship between the two.
WebQuadratic, Cubic (polynomial) If your data fluctuates (goes up and down) and resembles a curved line, choose quadratic or cubic. These are part of what's called the polynomial trend lines. Quadratic (Order 2 polynomial trend line) has one curve in the trend line. Cubic (Order 3) has two curves. Exponential, Logarithmic, Power
