sherpa.utils.guess.guess_bounds(x: ndarray, xhi: Literal[False]) → ValueAndRange

Guess the bounds of a parameter from the independent axis.

Parameters:

xarray_like: The axis values.
xhibool, optional: When True, the return value is two dictionaries, with values set to 1/3 and 2/3 along the axis, otherwise a single dictionary, with a value set to the mid-point is returned.

Returns:

ansdict or (dict, dict): When xhi is True then two dictionaries are returned, otherwise one. The keys are ‘val’, ‘min’, and ‘max’.
