## Array Quality Weights

### Description

Estimates relative quality weights for each array in a multi-array experiment with replication.

### Usage

    arrayWeightsQuick(y, fit)

### Arguments

`y` | the data object used to estimate `fit`. Can be of any class which can be coerced to matrix, including `matrix`, `MAList`, `marrayNorm` or `exprSet`.
`fit` | `MArrayLM` fitted model object

### Details

Estimates the relative reliability of each array by measuring how well the expression values for that array follow the linear model.

This is a quick and dirty version of `arrayWeights`.

### Value

Numeric vector of weights of length `ncol(fit)`.
