OK. Thank you for pointing out my mistake.

I still have my original question. How does the output relate to estimating the parameters of a given density? I read that for a gausian kernal:

bw.nrd0 implements a rule-of-thumb for choosing the bandwidth of a Gaussian kernel density estimator. It defaults to 0.9 times the minimum of the standard deviation and the interquartile range divided by 1.34 times the sample size to the negative one-fifth power (= Silverman's ‘rule of thumb’

But how does that relate to say a Poisson distribution or a two-parameter distribution like a normal, beta, or binomial distribution?

Thank you.

Kevin
