For\n            more information, see \"Parameter Keyword Arguments\" further down.\n\n            If you work with array parameters a lot, have a look at the static\n            initializer method :meth:`from_array_func`, which adds some\n            convenience and safety to this use case.\n\n        **Builtin Keyword Arguments:**\n\n            - **throw_nan**: set fcn to raise RuntimeError when it\n              encounters *nan*.

If set, this is used to detect\n              parameter names instead of iminuit's function signature detection.\n\n            - **print_level**: set the print_level for this Minuit. 0 is quiet.\n              1 print out at the end of MIGRAD/HESSE/MINOS. 2 prints debug messages.\n\n            - **errordef**: Optional. See :attr:`errordef` for details on\n              this parameter. If ""set to `None` (the default), Minuit will try to call\n              `fcn.errordef` and `fcn.default_errordef()` (deprecated) to set the error\n              definition. If this fails, a warning is raised and use a value appropriate\n              for a least-squares function is used.\n\n            - **grad**: Optional. Provide a function that calculates the\n              gradient analytically and returns an iterable object with one\n              element for each dimension. If None is given MINUIT will\n              calculate the gradient numerically. (Default None)\n\n            - **use_array_call**: Optional. Set this to true if your function\n              signature accepts a single numpy array of the parameters. You\n              need to also pass the `name` keyword then to\n              explicitly name the parameters.\n\n        **Parameter Keyword Arguments:**\n\n            iminuit allows user to set initial value, initial stepsize/error, limits of\n            parameters and whether the parameter should be fixed by passing keyword\n            arguments to Minuit.\n\n            This is best explained through examples::\n\n                def f(x, y):\n                    return (x-2)**2 + (y-3)**2\n\n            * Initial value (varname)::\n\n                #initial value for x and y\n                m = Minuit(f, x=1, y=2)\n\n            * Initial step size (fix_varname)::\n\n                #initial step size for x and y\n                m = Minuit(f, error_x=0.5, error_y=0.5)\n\n            * Limits (limit_varname=tuple)::\n\n                #limits x and y\n                m = Minuit(f, limit_x=(-10,10), limit_y=(-20,20))\n\n            * Fixing parameters::\n\n                #fix x but vary y\n                m = Minuit(f, fix_x=True)\n\n            .. note::\n\n                You can use dictionary expansion to programmatically change parameters.::\n\n                    kwargs = dict(x=1., error_x=0.5)\n                    m = Minuit(f, **kw""args)\n\n                You can also obtain fit arguments from Minuit object for later reuse.\n                *fitarg* will be automatically updated to the minimum value and the\n                corresponding error when you ran migrad/hesse.::\n\n                    m = Minuit(f, x=1, error_x=0.5)\n                    my_fitarg = m.fitarg\n                    another_fit = Minuit(f, **my_fitarg)\n\n        ";

It is\n        more convenient to use for functions that accept a numpy array.\n\n        **Arguments:**\n\n            **fcn**: The function to be optimized.

Initial step sizes.\n            Scalars are automatically broadcasted to the length of the\n            start sequence.\n\n            **limit**: Optional sequence of limits that restrict the range in\n            which a parameter is varied by minuit. Limits can be set in\n            several ways. With inf = float(\"infinity\") we get:\n\n            - No limit: None, (-inf, inf), (None, None)\n\n            - Lower limit: (x, None), (x, inf) [replace x with a number]\n\n            - Upper limit: (None, x), (-inf, x) [replace x with a number]\n\n            A single limit is automatically broadcasted to the length of the\n            start sequence.\n\n            **fix**: Optional sequence of boolean values.

It accept a numpy\n            array of the parameters.

How\n        MIGRAD works is described in the `MINUIT paper`_.\n\n        **Arguments:**\n\n            * **ncall**: integer (approximate) maximum number of call before\n              MIGRAD will stop trying. Default: 0 (indicates to use MIGRAD's\n              internal heuristic). Using nsplit > 1 requires ncall > 0.\n              Note: MIGRAD may slightly violate this limit,\n              because it checks the condition only after a full iteration of the\n              algorithm, which usually performs several function calls.\n\n            * **resume**: boolean indicating whether MIGRAD should resume from\n              the previous minimiser attempt(True) or should start from the\n              beginning(False). Default True.\n\n            * **nsplit**: split MIGRAD in to *split* runs. Max fcn call\n              for each run is ncall/nsplit. MIGRAD stops when it found the\n              function minimum to be valid or ncall is reached. This is useful\n              for getting progress. However, you need to make sure that\n              ncall/nsplit is large enough. Otherwise, MIGRAD will think\n              that the minimum is invalid due to exceeding max call\n              (ncall/nsplit). Default 1(no split).\n\n            * **precision**: override miniut own's internal precision.\n\n        **Return:**\n\n            :ref:`function-minimum-sruct`, list of :ref:`minuit-param-struct`\n        ";

It scans the negative log-likelihood or\n        (equivalently) the least-squares cost function around the minimum\n        to construct an asymmetric confidence interval. This interval may\n        be more reasonable when a parameter is close to one of its\n        parameter limits. As a rule-of-thumb: when the confidence intervals\n        computed with HESSE and MINOS differ strongly, the MINOS intervals\n        are to be preferred. Otherwise, HESSE intervals are preferred.\n\n        Running MINOS is computationally expensive when there are many\n        fit parameters. Effectively, it scans over *var* in small steps\n        and runs MIGRAD to minimise the FCN with respect to all other free\n        parameters at each point. This is requires many more FCN evaluations\n        than running HESSE.\n\n        **Arguments:**\n\n            - **var**: optional variable name to compute the error for.\n              If var is not given, MINOS is run for every variable.\n            - **sigma**: number of :math:`\\sigma` error. Default 1.0.\n            - **maxcall**: limit the number of calls made by MINOS.\n              Default: 0 (uses an internal heuristic by C++ MINUIT).\n\n        **Returns:**\n\n            Dictionary of varname to :ref:`minos-error-struct`, containing\n            all up to now computed errors, including the current request.\n\n        ";
