gnuplot_formula – full formula of the model, gnuplot style.fit_history – info about recorded parameter sets.errors – estimated uncertainties of parameters.data – number of points, data filename and title.confidence level – confidence limits for given confidence level.compiler – options used when compiling the program.The following info arguments are recognized: width_correction See Guessing Initial Parameters. verbosity Possible values: -1 (silent), 0 (normal), 1 (verbose), 2 (very verbose). Irresponsive program is a frustrating experience. The program’s window notably slows down fitting, and on the other hand This option was introduced, because on one hand frequent refreshing of Remain not changed for this time (in seconds). refresh_period During time-consuming computations (like fitting) user interface can Pseudo-random numbers is different each time. Is set to 0, the seed is based on the current time and a sequence of Seed for a new sequence of pseudo-random numbers can be set using the In some situations one may want to have repeatableĪnd predictable results of the fitting, e.g. Randnormal in data expressions use a pseudo-random pseudo_random_seed Some fitting methods and functions, such as (finish program – ensures that no error can be overlooked). Other possible values are nothing (do nothing) and exit (default) and the error happens in script, the script is stopped. Of numbers to 3 digits after the decimal point. It takes as a valueĪ format string, the same as sprintf() in the C language.įor example set numeric_format='%.3f' changes the precision numeric_format Format of numbers printed by the info command. nm_* Setting to tune the Nelder-Mead downhill simplexįitting method. max_wssr_evaluations See Fitting Related Commands. max_fitting_time Stop fitting when this number of seconds of processor time is exceeded. log_full Log output together with input (0/1). lm_* Setting to tune the Levenberg-Marquardt fitting method. height_correction See Guessing Initial Parameters. function_cutoff See description in the chapter about model. fitting_method See Fitting Related Commands. fit_replot Refresh the plot when fitting (0/1). You may need to decrease it when working with very small numbers. Numbers should have some tolerance, and the tolerance should be tailored (it is well known that due to rounding errors the equality test for two epsilon The ε value used to test floating-point numbers a and b for equality domain_percent See the section about variables.

Possible values: sqrt max( y 1/2, 1) and one (1). default_sigma Default y standard deviation. cwd Current working directory or empty string if it was not set explicitely.Īffects relative paths.

The list of available options: autoplot See autoplot. With fitting_method=levenberg_marquardt, verbosity=quiet fit 10 # and now the default method is back Nelder-Mead # multiple comma-separated options can be given With fitting_method = levenberg_marquardt fit 10

Set fitting_method = nelder_mead_simplex # change the method # change the method only for this one fit command Info set fitting_method # show the current fitting method
