标题： Comments on Likelihood fits with variable resolution

摘要： 无分箱似然拟合在物理学中很常见，通常涉及具有多个组件的复杂函数。 我们讨论了在拟合中使用的模板不是固定而是依赖于事件可观测量的情况下的潜在陷阱，这种情况发生在测量分辨率依赖于事件时，并介绍了避免这些情况的方法。 显示英文摘要

摘要： Unbinned likelihood fits are frequent in Physics, and often involve complex functions with several components. We discuss the potential pitfalls of situations where the templates used in the fit are not fixed but depend on the event observables, as it happens when the resolution of the measurement is event--dependent, and the procedure to avoid them.
