WebAug 15, 2024 · However, modeling the spike residuals as a Gaussian distribution dramatically underestimates the fraction of spikes that are located away from the cluster center (Fig. 6 B and C). ... If we analyze these irregularly-shaped clusters as stationary distributions, then some units will appear to overlap even though they remain well … Data follow a Gaussian distribution when scatter is caused by the sum of many independent and equally weighted factors. A frequency distribution (histogram) created from Gaussian data will look like a bell-shaped Gaussian distribution. See more The data you fit must be in the form of a frequency distribution on an XY table. The X values are the bin center and the Y values are the number of observations. If you start with a … See more Y=Amplitude*exp(-0.5*((X-Mean)/SD)^2) Amplitudeis the height of the center of the distribution in Y units. Meanis the X value at the center of the … See more The area under a Gaussian distribution equals Amplitude*SD/0.3989. That constant equals the reciprocal of the square root of two pi. See more
