Approximation of the of the value of the distribution function of a Gaussian quadratic form based on its first three moments.

1 | ```
pearson.qf(x, moment, lower.tail = TRUE, verbose = FALSE)
``` |

`x` |
value at which the distribution function is to be evaluated |

`moment` |
vector with the mean, variance and skewness of the quadratic form |

`lower.tail` |
logical, indicating of the lower or upper tail of the distribution function should be calculated |

`verbose` |
logical, if |

This is Pearson's approximation for Gaussian quadratic forms as stated in [4] (equation (4.65) in arXiv:1808.07280v2)

For the theoretic background see the reference [4] given on the main help page of this package: multivariance-package.
