croissance.estimation.regression.exponential(x, a, b, c)

croissance.estimation.regression.fit_exponential(series, *, p0=(1.0, 0.01, 0.0), n0: float = None)

Fits an exponential to a series. First attempts an exponential fit in linear space using p0, then falls back to a fit in log space to attempt to find parameters p0 for a linear fit; if all else fails returns the linear fit.
