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

Guess the bounds of a parameter from the independent axis.

Parameters:

x (array_like) – The axis values.
xhi (bool, 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.
