Description Usage Arguments Details Value References Examples

This function takes the particular list of possible hypthesis to correct for multiple testing, as defined in Li (2008).

1 | ```
adjustLi(pvalues)
``` |

`pvalues` |
Raw p-values in either a vector or a matrix. Note that in case the p-values are in a matrix, all the values are used for the correction. Therefore, if the matrix contains repeated values (as those output by some methods in this package), the repetitions have to be removed. |

The test has been implemented according to the version in Garcia *et al.* (2010), page 2680-2682. This is a simple procedure that provides good results when the highest p-value corrected is below 0.5. However, When the highest p-value is close to 1 the correction is extremely conservative. Actually, when the highest p-value is 1, all the corrected p-values are set at 1. Therefore, it is not advisable to be used under these circumstances.
