##### Using the CHISQ.INV.RT function:

The arguments for the CHISQ.INV.RT function are:

Argument | Required? | Description |
---|---|---|

probability | Required | A probability associated with the chi-squared distribution. |

deg_freedom | Required | The number of degrees of freedom. |

##### A few more things:

• If either argument is nonnumeric, CHISQ.INV.RT returns the #VALUE! error value. |

• If probability < 0 or probability > 1, CHISQ.INV.RT returns the #NUM! error value. |

• If deg_freedom is not an integer, it is truncated. |

• If deg_freedom < 1, CHISQ.INV.RT returns the #NUM! error value. |

• Given a value for probability, CHISQ.INV.RT seeks that value x such that CHISQ.DIST.RT(x, deg_freedom) = probability. Thus,
precision of CHISQ.INV.RT depends on precision of CHISQ.DIST.RT. CHISQ.INV.RT uses an iterative search technique. If the search has not converged after 64 iterations,
the function returns the #N/A error value. |
