## Density Function Of The Heavy-Headed Distribution

### Description

This function gives the values of the density of the heavy-headed distribution.

### Usage

dhh(x, a=0, b=1, alpha=0.1)


### Arguments

 x x is a vector of real values, at which the values of the density will be calculated. a,b The interval (a,b) is the support of the distribution. The default values for a and b are 0 and 1, respectively. alpha It is a positive parameter of the distribution. Its default value is set to be 0.1. When alpha = 1, the distribution is uniform. When alpha > 1, the density at a is zero.

### Details

See the references.

### Value

It returns the values of the density at x.
