Systematic data smoothing by using Bezier curves

3 Systematic data smoothing by using Bezier curves 

The estimation of errors, as described in the previous section, is the only way to verify the quality of statistical data obtained by experiment or computer simulation. With the methods described, it is simple to obtain a reliable error estimate for a single quantity such as an expectation value O of a quantity O. However, it is often also desirable to interpret the curve behavior of a function in its argument space. The microcanonical analysis introduced in Section 2.7, for example, requires precise information about the monotony of energy-dependent quantities, such as the microcanonical entropy S E). We can, of course, measure the entropy for each energy bin and obtain and average over many samples or
