if a gaussian integral is used it is a better fit when is it preferable to fit an integral why is it better to fit a signal with integral instead of purely data? why would it be better to fit to the integral or the data itself why would it be desirable to fit to the integral of the signal why is it necessary to fit data to integral why might it be better to fit data to the integral why is it better to fit to integral or absolute data why is integral fitting more reliable why should an integral fit data why would it be better to fit to the integral of the signal than to the data itself why does it matter what the integral of the data is why is it better to fit to the integral of the data when does it become necessary to fit the integral of the signal when might it be preferable to fit to the integral of the data? why fit to data in an equation why is it better to fit the integral of the data than the data itself? why does the integral of the signal matter why fit to integral why does it make a signal more reliable
