scHOT_estimatePvalues {scHOT} | R Documentation

## scHOT_estimatePvalues

### Description

Estimate p-values based on already run permutation tests

### Usage

    scHOT_estimatePvalues(
      scHOT,
      usenperm_estimate = FALSE,
      nperm_estimate = 10000,
      maxDist = 0.1,
      plot = FALSE,
      verbose = FALSE
    )

### Arguments

`scHOT` | A scHOT object
`usenperm_estimate` | Logical (default FALSE) if number of neighbouring permutations should be used, or if difference of global higher order statistic should be used
`nperm_estimate` | Number of neighbouring permutations to use for p-value estimation
`maxDist` | max difference of global higher order statistic to use for p-value estimation (default 0.1)
`plot` | A logical input indicating whether the results are plotted
`verbose` | A logical input indicating whether the intermediate steps will be printed

### Value

scHOT A scHOT object with results stored in scHOT_output slot

### Examples

     sce_MOB_subset <- MOB_subset$sce_MOB_subset
     scHOT_spatial <- scHOT_buildFromSCE(sce_MOB_subset,

    scHOT_spatial <- scHOT_calculateHigherOrderTestStatistics(
      scHOT_spatial,
      higherOrderSummaryFunction = sd)
