This procedure chooses the p-value threshold for feature selection in a similar fashion to hct_empirical. However, it is based on the Beta distribution of the p-values. Only the features whose p-values are less than the thresold will be included in the classifier.

hct_beta(pvalue, p, n)

`pvalue` |
A vector containing the p*alpha_0 smallest p-values; typically alpha_0=0.10 |

`p` |
The number of the features in total. |

`n` |
The total sample size for the two groups. |
