1 | ```
MCHdiag(at, Sigma.t, m = 10)
``` |

`at` |
A T-by-k matrix of residuals for a k-dimensional asset return series |

`Sigma.t` |
The fitted volatility matrices. The dimension is T-by-k^2 matrix |

`m` |
The number of lags used in the tests. Default is 10. |

The four test statistics are given in Tsay (2014, Chapter 7)
