SPM ANOVA (F-test)

Performs SPM F-test for comparing multiple groups.

Usage

spmAnova(x, groups, alpha = 0.05)

Arguments

x

A PhysioExperiment object or matrix (time x observations).

groups

Factor or list indicating group membership.

alpha

Significance level.

Value

A list of class "spm_result" containing F-statistics and clusters.

Examples

# Three-group comparison
set.seed(123)
g1 <- matrix(rnorm(100 * 8), nrow = 100)
g2 <- matrix(rnorm(100 * 8), nrow = 100) + 0.5
g3 <- matrix(rnorm(100 * 8), nrow = 100) + 1.0

data <- cbind(g1, g2, g3)
groups <- factor(rep(c("A", "B", "C"), each = 8))

pe <- PhysioExperiment(assays = list(values = data), samplingRate = 100)
result <- spmAnova(pe, groups = groups)
