PSI_Statistic {EventPointer} | R Documentation

## PSI_Statistic

### Description

Statistical analysis of the alternative splicing events. This function takes as input the values of PSI. Perform a statistical analysis based on permutation test

### Usage

    PSI_Statistic(PSI, Design, Contrast, nboot)

### Arguments

`PSI` | A matrix with the values of the PSI.
`Design` | The design matrix for the experiment.
`Contrast` | The contrast matrix for the experiment.
`nboot` | The number of random analysis.

### Value

The output of these functions is a list containing: two data.frame (deltaPSI and Pvalues) with the values of the deltaPSI and the p.values for each contrast, and a third element (LocalFDR) with the information of the local false discovery rate.

### Examples

          data(ArraysData)
          PSI_Arrays_list<-EventPointer:::getPSI(ArraysData)
          PSI_Arrays <- PSI_Arrays_list$PSI
          Design <- matrix(c(1,1,1,1,0,0,1,1),nrow=4)
          Contrast <- matrix(c(0,1),nrow=1)

          # Statistical analysis:

          table <- PSI_Statistic(PSI_Arrays,Design = Design, Contrast = Contrast, nboot = 50)
