`x` |

`y` |
vector with names. |

`tree` |
a phylogenetic tree in |

`method` |

`lambda` |
value of |

`fixed` |
logical value indicating whether or not |

`h0` |
null hypothesis for |

`object` |
for |

`...` |
optional arguments for S3 methods. |

Optionally jointly estimates lambda if `method="lambda"`

. Likelihood optimization of lambda is performed using `optimize`

on the interval (0,1). Note that some statistician think there is *never* a condition in which a reduced-major-axis regression should be used.

The statistical hypothesis testing is based on Clarke (1980; reviewed in McArdle 1988), which differs from some other implementations of non-phylogenetic major axis regression in R.

An object of class `"phyl.RMA"`

consisting of a list with the following components:

`RMA.beta` |
a vector of RMA regression coefficients. |

`V` |
a VCV matrix for the traits. |

`lambda` |
fitted value of lambda ( |

`logL` |
log-likelihood ( |

`test` |
a vector containing results for hypothesis tests on |

`resid` |
a vector of residuals for |
