# Compute Additive Coefficient From Three Genotype Probabilities

### Description

`get.add.coef.from.3.genoprobs`

should not typically be called by a user.
It is used to reliably set up model coefficients from genotype probabilities.

### Usage

1 | ```
get.additive.coef.from.3.genoprobs(paa, pab, pbb)
``` |

### Arguments

`paa` |
A vector of length n giving the probability of AA-type for each individual, or a matrix or data.frame of dimension n-by-3 giving probability of AA-type and the probability of AB-type and the probability of BB-type for each individual. |

`pab` |
A vector of length n giving the probability of AB-type for each individual,
or missing if |

`pbb` |
A vector of length n giving the probability of BB-type for each individual,
or missing if |

### Details

none

### Value

Additive coefficient vector.
