| dnormp {normalp} | R Documentation |
Density function for the normal of order p distribution with location parameter mu,
scale parameter sigmap and structure parameter p.
dnormp(x, mu=0, sigmap=1, p=2, log=FALSE)
x |
Vector of quantiles. |
mu |
Vector of location parameters. |
sigmap |
Vector of scale parameters. |
p |
Structure parameter. |
log |
Logical; if TRUE, the density is given as log(density). |
If mu, sigmap or p are not specified they assume the default values 0, 1 and 2,
respectively.
The normal of order p distribution has density function
f(x) = 1/(2 p^(1/p) Gamma(1+1/p) sigmap) exp{-|x - mu|^p/(p sigmap^p)}
where mu is the location parameter, sigmap the scale parameter and p the structure parameter. When p=2 the Normal of Order p Distribution becomes the Normal (Gaussian) Distribution, when p=1 the Normal of Order p Distribution becomes the Laplace Distribution, when p->infinity the Normal of Order p Distribution becomes the Uniform Distribution.
dnormp gives the density function of a normal of order p distribution.

## Compute the density for a vector x with mu=0, sigmap=1 and p=1.5
## At the end we have the graph of the Normal of order p density function with p=1.5
x <- c(-1, 1)
f <- dnormp(x, p=1.5)
print(f)
plot(function(x) dnormp(x, p=1.5) , -4, 4,
