Many hypothesis tests for two means of percentages.

1 | ```
percent.ttests(x, y, logged = FALSE)
``` |

`x` |
A numericalmatrix with the percentages of the first sample. Any value between 0 and 1 (inclusive) is allowed. |

`y` |
A numerical matrix with the percentages of the first sample. Any value between 0 and 1 (inclusive) is allowed. |

`logged` |
Should the p-values be returned (FALSE) or their logarithm (TRUE)? |

This is the `prop.reg`

but with a single categorical predictor which has two
levels only. It is like a t-test for the means of two samples haivng percentages.

A matrix with three columns, the phi parameter, the test statistic and its associated p-value.
