The error of an estimate or prediction is its deviation from the true value, which may be unobservable (e.g., regression parameters), or observable (e.g., future realizations). Use the [error-message] tag to ask about software errors.

Estimating errors for parameters from a nonlinear fitting procedure
What puzzles me is the last step to calculate the relative error:
$\delta a_j = \sqrt{\frac{f(x, \vec{a}_\text{fit})}{50 - N} \vert C_{j,j} \vert } \frac{1}{a_j}$
The value $f$ is the minimum value, … $a_j$ is the parameter for which the error is to be estimated.
From a dimensional point of view, the result is a percentage, which is fine, but the denominator $50 - N$ puzzles me. …
