X Log X
A constant plus a term in x ln x. Use it when theory predicts this form, for example the running time of an algorithm that grows as n log n.
Fit the example dataStart with your own data
Example: simulated sorting times against list length, 9 points with y uncertainties, opened as a new copy you can edit.
Parameters
- Value of y at x = 1, where ln x = 0.
- Coefficient of x ln x.
Tips
- x must be positive.
- To report the coefficient of x log₂ x instead, multiply B by ln 2.
- With no uncertainties selected, the goodness of fit is R², because the model is linear in its parameters.
