Densities are not probabilities - they can exceed one. To confirm this, plug in some values into the normal density formula with small values of sigma.

I met a strange problem when using kdensity and hope someone could help me.
Thanks in advance.

When i use kdensity to draw density graph of my data, the scale of the
probablity excees one.  Is this the problem of the command or anything?


Best,

Yue Li
