For EASY-FIT Express 2.0Publisher's description
Model functions are defined in a modeling language called PCOMP and are interpreted and evaluated during runtime.
Features:
general
arbitrary fitting criteria depending on parameters to be estimated
additional nonlinear EQuality or inequality constraints
second Independent model variable called concentration
numerical routines
Gauss-Newton-type SQP methods, various versions
automatic differentiation
alternative norms (sum of absolute values, maximum of absolute values)
confidence intervals for estimated parameters, correlation and covariance Matrix
identification of significance levels for estimated parameters
extremely fast routines
user interface
convenient and flexible modeling language
'find' and 'filter' commands
