BootstrapRep | R Documentation |
Calculates the repeatability of the covariance matrix of the supplied data via bootstrap resampling
BootstrapRep(
ind.data,
ComparisonFunc,
iterations = 1000,
sample.size = dim(ind.data)[1],
correlation = FALSE,
parallel = FALSE
)
ind.data |
Matrix of residuals or individual measurements |
ComparisonFunc |
comparison function |
iterations |
Number of resamples to take |
sample.size |
Size of resamples, default is the same size as ind.data |
correlation |
If TRUE, correlation matrix is used, else covariance matrix. |
parallel |
if TRUE computations are done in parallel. Some foreach backend must be registered, like doParallel or doMC. |
Samples with replacement are taken from the full population, a statistic calculated and compared to the full population statistic.
returns the mean repeatability, that is, the mean value of comparisons from samples to original statistic.
