get_projection_results

sherpa.ui.get_projection_results()

Return the results of the last proj run.

Note

The conf function should be used instead of proj.

Returns:results Return type:sherpa.fit.ErrorEstResults object Raises:sherpa.utils.err.SessionErr – If no proj call has been made.

See also

conf()

Estimate confidence intervals for fit parameters.

proj()

Estimate confidence intervals for fit parameters.

get_proj_opt()

Return one or all of the options for the projection method.

set_proj_opt()

Set an option of the proj estimation object.

Notes

The fields of the object include:

datasets

A tuple of the data sets used in the analysis.

methodname

This will be ‘projection’.

iterfitname

The name of the iterated-fit method used, if any.

fitname

The name of the optimization method used.

statname

The name of the fit statistic used.

sigma

The sigma value used to calculate the confidence intervals.

percent

The percentage of the signal contained within the confidence intervals (calculated from the sigma value assuming a normal distribution).

parnames

A tuple of the parameter names included in the analysis.

parvals

A tuple of the best-fit parameter values, in the same order as parnames.

parmins

A tuple of the lower error bounds, in the same order as parnames.

parmaxes

A tuple of the upper error bounds, in the same order as parnames.

nfits
