Skew-Normal parameter computation
Description
Compute parameters and moments of skew normal distribution.
Usage
sn.location(mode, scale, shape)
sn.mean(dp)
sn.mode(dp)
sn.variance(scale, shape)
sn.skewness(shape)
sn.delta(shape)
sn.m0(shape)
Arguments
mode |
mode of skew normal distribution. |
scale |
skew normal scale parameter. |
shape |
skew normal shape parameter. |
dp |
3 element vector of (in order) location, scale, and shape parameters. |
Value
sn.location | location parameter computed from mode, scale, and shape. |
sn.mean | mean of the skew normal distribution. |
sn.mode | mode of the skew normal distribution. |
sn.variance | variance of the skew normal distribution. |
sn.skewness | skewness of the skew normal distribution. |
sn.delta | value used in other moment computations. |
sn.m0 | value used in mode computation. |
