RooNLLVar Class Reference

Class RooNLLVar implements a -log(likelihood) calculation from a dataset and a PDF.

PyROOT

RooNLLVar() constructor takes a RooCmdArg as argument also supports keyword arguments.

The NLL is calculated as

\[ \sum_\mathrm{data} -\log( \mathrm{pdf}(x_\mathrm{data})) \]

In extended mode, a \( N_\mathrm{expect} - N_\mathrm{observed}*log(N_\mathrm{expect}) \) term is added.

Compute probabilites of all data events.

Use faster batch interface.

Parameters

[in]

stepSize

Stride when moving through the dataset.

Note

For batch computations, the step size must be one.

Parameters

[in]	firstEvent	First event to be processed.
[in]	lastEvent	First event not to be processed.

Returns

Tuple with (Kahan sum of probabilities, carry of kahan sum, sum of weights)
