Fit bell curve to data
WebThe bell curve rule also knows as the 68 95 99 rule implies the following: About 68% of all the data lies within one standard deviation of the mean. Approximately 95% of all the data is within two standard deviations of the mean. Up to 99.7% of the data is within three standard deviations of the mean. Is the bell curve good or bad? WebMar 26, 2014 · The data is a distribution of signal over a rate (i.e. Y - Signal magnitude, X - time). I am trying to fit the distribution by transforming the function for the normal distribution PDF so that I can use it in a least squares fit of the data. This is what I do: I change: f (x) = 1/ (s*sqrt (2*pi)) * exp ( - ( (X - m).^2)./ (2*s^2) ); to:
