ddnorm | R Documentation |

This function returns the derivative(s) of the density function
of the normal (Gaussian) distribution with respect to the quantile,
evaluated at the quantile(s), mean(s), and standard deviation(s)
specified by arguments `x`

, `mean`

, and `sd`

, respectively.

```
ddnorm( x, mean = 0, sd = 1 )
```

`x` |
quantile or vector of quantiles. |

`mean` |
mean or vector of means. |

`sd` |
standard deviation or vector of standard deviations. |

numeric value(s): derivative(s) of the density function of the normal distribution with respect to the quantile
