defaultPrior {MAST} | R Documentation

## Initialize a prior to be used a prior for BayeGLMlike/BayesGLMlike2

### Description

Initialize a prior to be used a prior for BayeGLMlike/BayesGLMlike2

### Usage

    defaultPrior(names)

### Arguments

`names` | character vector of coefficients. The '(Intercept)' will be ignored.

### Value

3d array, with leading dimension giving the prior 'loc'ation, 'scale' and degrees of freedom (df), second dimension giving the component ('C'ontinuous or 'D'iscrete) and trailing dimension giving the coefficient to which the prior applies. The location is initialized to be 0, the scale to 2, and degrees of freedom of 1, following the default of bayesglm.

### Examples

    dp <- defaultPrior('Stim.ConditionUnstim')
    ## Not run:
    data(vbetaFA)
    zlmVbeta <- zlm(~ Stim.Condition, vbetaFA, method='bayesglm', coefPrior=dp)

    ## End(Not run)
