Gauss mean std

WebThe Gaussian distribution is a continuous function which approximates the exact binomial distribution of events. The Gaussian distribution shown is normalized so that the sum over all values of x gives a probability of 1. The nature of the gaussian gives a probability of 0.683 of being within one standard deviation of the mean. WebMar 28, 2024 · Mean of the Gaussian. stddev float or Quantity. Standard deviation of the Gaussian with FWHM = 2 * stddev * np.sqrt(2 * np.log(2)). Other Parameters: fixed a dict, optional. A dictionary {parameter_name: boolean} of parameters to not be varied during fitting. True means the parameter is held fixed.
