diag_ljungbox: Ljung-Box
In SMAC-Group/exts: Experimental Features for Time Series

Performs the Ljung-Box test to assess the Null Hypothesis of Independence in a Time Series

diag_ljungbox(x, order = NULL, stop_lag = 20, stdres = FALSE, ...)

## S3 method for class 'Arima'
diag_ljungbox(x, stop_lag = 20, stdres = FALSE, ...)

## Default S3 method:
diag_ljungbox(x, order = NULL, stop_lag = 20,
  stdres = FALSE, ...)

`x`	A `arima` or data set.
`order`	A `integer` indicating the degrees of freedom. If 'x' is not a series of residuals, then set equal to 0.
`stop_lag`	A `integer` indicating the length of lags that should be calculated.
`stdres`	A `boolean` indicating whether to standardize the residualizes (e.g. res/sd(res)) or not.
