This function implements the mean method of test equating as described in Kolen and Brennan (2004).

1 |

`sx` |
A vector containing the observed scores of the sample taking test |

`sy` |
A vector containing the observed scores of the sample taking test |

`scale` |
Either an integer or vector containing the values on the scale to be equated. |

The function implements the mean method of equating as described in Kolen and Brennan (2004). Given observed scores
*sx* and *sy*, the functions calculates

*phi(x;mu_x,mu_y)=x-mu_x+mu_y*

where *mu_x* and *mu_y* are the score means on test *X* and *Y*, respectively.

A two column matrix with the values of *phi()* (second column) for each scale value `x`

(first column)
