A free parameter is a variable used in a mathematical model and for scientific modelling.

This model does however still have a number of unknown free parameters which can be estimated using system identification.

The model has no free parameters that need manual tuning.

This is analogous to desiring fewer free parameters in a fundamental theory.

If overdispersion is a feature, an alternative model with additional free parameters may provide a better fit.

Note that this model has an additional free parameter - namely the variance of the normal variable.

As we know k* is a function of free fitting parameter and the contact resonances.

The free parameter is then simply the average difference between the two items' ratings.

Since there are two free parameters, at most only two coefficients can be made to equal unity.

The number of free parameters in a nondimensionalized form of a system increases with its order.
