weitrix_dispersions {weitrix} | R Documentation

## Calculate row dispersions

### Description

Calculate the dispersion of each row. For each observation, this value divided by the weight gives the observation's variance.

### Usage

    weitrix_dispersions(weitrix, design = ~1)

### Arguments

`weitrix` | A weitrix object, or an object that can be converted to a weitrix with `as_weitrix`.
`design` | A formula in terms of `colData(weitrix` or a design matrix, which will be fitted to the weitrix on each row. Can also be a pre-existing Components object, in which case the existing fits (`design$row`) are used.

### Value

A numeric vector.

### Examples

    # Using a model just containing an intercept
    weitrix_dispersions(simwei, ~1)

    # Allowing for one component of variation, the dispersions are lower
    comp <- weitrix_components(simwei, p=1, verbose=FALSE)
    weitrix_dispersions(simwei, comp)
