residuals¶
- nbi_stat.residuals(x, y, f, p, ey=None)[source]¶
Calculate the residuals with respect to some function
This will calculate the residuals of the data sample
{x_,y_,delta_i | i=1,…N}
with respect to the function f(x,p), where p are the parameters of the function
Note, points with delta_i=0 are explicitly ignored
- Parameters:
x (array-like) – Independent variable
y (array-like) – Dependent variable
ey (array-like) – Uncertainty on y
f (callable) – function
p (array-like) – function parameters
- Returns:
x (array-like) – Places where the residuls have been evaluated
r (array-like) – Residuals
