pdfnor {lmomco} | R Documentation |
This function computes the probability density function
of the Normal distribution given parameters of the distribution computed
by parnor
. The probability density function of the distribution is
f(x) = frac{1}{σ sqrt{2π}} e^{-(x-μ)^2/(2σ^2)} mbox{,}
where f(x) is the probability density for quantile x,
μ is the arithmetic mean, and σ is the standard deviation, and
Phi is the cumulative distribution function of the standard normal
distribution. The R-function pnorm
is used.
