nullDistri {OVESEG} | R Documentation

## Probability of one group being upregulated under null

### Description

This function estimates probabilities of any one group being upregulated than other groups under null hypotheses.

### Usage

    nullDistri(ppnull)

### Arguments

`ppnull` | a list returned by `postProbNull` or `OVESEGtest`.

### Details

The probability of one group being upregulated under null hypotheses is calculated by accumulating and normalizing genewise posterior probability of null hypotheses. The group with higher probability tends to get more False Positive MGs.

### Value

a numeric vector indicating probabilities of each group being upregulated than others under null hypotheses.

### Examples

    data(RocheBT)
    ppnull <- postProbNull(RocheBT$y, RocheBT$group, alpha='moderated')
    pk <- nullDistri(ppnull)
