WebApr 11, 2015 · The histogram can be used as an approximation to the probability density (PDF), but for that you need to scale it correctly. The integral of a PDF from -infinity to +infinity has to result in 1, so we need to scale the histogram accordingly. You can still use the hist command, but instead of using it to generate the histogram plot, we get the ... WebMar 18, 2013 · I want some data to fit the corresponding Gaussian distribution.
