# Probabilty density function of skewed symmetric model.

### Description

Computes pdf of the skewed symmetric model.

### Usage

1 |

### Arguments

`x` |
scalar or vector of values to compute the pdf. |

`spec1` |
a character string specifying the parent distribution |

`arg1` |
list of arguments/parameters of the parent distribution |

`spec2` |
a character string specifying the parent distribution |

`arg2` |
list of arguments/parameters of the parent distribution |

`log` |
logical; if |

### Details

The pdf of skewed symmetric model has a general form of:

*
f(x) = 2h(x)G(x), \quad -∞ < x < ∞
*

where *h(x)* and *G(x)* are the pdf and cdf of parent distributions, respectively.

### Value

An object of the same length as `x`

, giving the pdf values computed at `x`

.
