Sample autocorrelation

`autocorr(y)`

`autocorr(y,numLags)`

`autocorr(y,numLags,numMA,numSTD)`

`acf = autocorr(y)`

`acf = autocorr(y,numLags)`

`acf = autocorr(y,numLags,numMA,numSTD)`

```
[acf,lags,bounds]
= autocorr(___)
```

`autocorr(`

plots
the sample autocorrelation
function (ACF) of the univariate, stochastic time series `y`

)`y`

with
confidence bounds.

To plot the ACF without confidence bounds, set `numSTD`

to
0.
