associationTest {tradeSeq} | R Documentation

## Perform statistical test to check whether gene expression is constant across pseudotime within a lineage

### Description

Assess whether gene expression is associated with pseudotime.

### Usage

    associationTest(models, ...)

    ## S4 method for signature 'SingleCellExperiment'
    associationTest(models, global = TRUE,
      lineages = FALSE)

    ## S4 method for signature 'list'
    associationTest(models, global = TRUE,
      lineages = FALSE)

### Arguments

`models` | the list of GAMs, typically the output from `fitGAM`.
`...` | parameters including:
`global` | If TRUE, test for all lineages simultaneously.
`lineages` | If TRUE, test for all lineages independently.

### Value

A matrix with the wald statistic, the number of df and the p-value associated with each gene for all the tests performed. If the testing procedure was unsuccessful, the procedure will return NA test statistics and p-values.

### Examples

    data(gamList, package = "tradeSeq")
    associationTest(gamList, global = TRUE, lineages = TRUE)
