stats_dens_logistic — Probability density function of the logistic distribution

### 说明

stats_dens_logistic ( float `$x` , float `$ave` , float `$stdev` ) : float

Returns the probability density at `x`, where the random variable follows the logistic distribution of which the location parameter is `ave` and the scale parameter is `stdev`.

### 参数

`x`

  The value at which the probability density is calculated

`ave`

  The location parameter of the distribution

`stdev`

  The shape parameter of the distribution

### 返回值

The probability density at `x` or `FALSE` for failure.
