Ansatz
Ansatz is a German language term often used by physicists. An ansatz is an assumed form for a mathematical function that is not based on any underlying theory or principle.
For example, given a set of experimental data that looks to be clustered about a line, a linear ansatz could be made to find the parameters of the line by a least squares curve fit . Variational approximation methods use ansatzes and then fit the parameters.
