2 by 2 crossover design. Test the treatment-by-period interaction (carry-over effect)

H0: the difference of the two sequence carry-over effects is equal to 0

Ha: not equal to 0

The test is finding whether there is a difference between the carry-over effect for sequence AB and BA.

1 | ```
Carry.Over(alpha, beta, sigma1, sigma2, gamma)
``` |

`alpha` |
significance level |

`beta` |
power = 1-beta |

`sigma1` |
standard deviation of sequence AB |

`sigma2` |
standard deviation of sequence BA |

`gamma` |
the difference of carry-over effect between sequence AB and BA |
