A kernel density curve may follow the shape of the distribution more closely. To construct a normal kernel density curve, one parameter is required: the bandwidth .The value of determines the degree ...

Which normal density curve best approximates the sample histogram? The answer suggested here is the normal curve that minimizes the integrated squared deviation between the histogram and the normal ...

In my previous post about a floating Saturn, I hinted that I could write about the methods we can use to find the density of Saturn. Oh, and once again, the density of Saturn is lower than the density ...
