Extrapolation: Linear¶

Extrapolate as: I(q) = B + m * q

class jldesmear.api.extrap_linear.Extrapolation[source]¶

I(q) = B + m*q

Parameters:	q (float) – magnitude of scattering vector
Returns:	value of extrapolation function at q
Return type:	float

fit_result(reg)[source]¶

Determine the results of the fit and store them as the set of coefficients in the self.coefficients dictionary. Called from fit().

Note:	must override in subclass otherwise `fit_result()` will throw an exception
Parameters:	reg (StatsRegClass object) – statistics registers (created in `fit()`)
