"WebOct 20, 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. " - Polynomial interpolation in excel
