@swift-ci Please smoke test and merge. |
This, somewhat questionably, fits the polynomial model and the exponential model, and then chooses the one with the best R^2. However, no matter how statistically valid this is, it works reasonably in practice. Slow growing things sometimes get classified as 1.0^n or 1.1^n, but these are either spurious or not relevant, and so a similar thresholding to the polynomial fit is used.
