The chemical process models which are created by HSC-Sim are often based on experimental data expressed in the function format. The HSC-Sim Data Fit module may be used to convert experimental data points into functions. Of course, these functions may also be created by using some other data fitting applications, however, the built-in HSC-Sim Data Fit module offers more flexible links to the other HSC-Sim modules.

The HSC-Sim Data Fit module offers versatile multi-regression, curve fitting and statistical properties for linear and nonlinear functions. Up to 20 independent variables (X1, X2, X3, …) and 100 parameters (A, B, C, …) may be used in these functions (models). The fitting may be based on up to 65 536 data point sets. The user may specify the function formula freely or use one of the 370 built-in functions. Data Fit utilizes the robust Levenberg-Marquardt method with double precision to perform non-linear regression.
The Fit module may be started from the Sim module menu.
