MeanMatrixStatistics: Calculate mean values for various matrix statistics

Description

Calculates: Mean Squared Correlation, ICV, Autonomy, ConditionalEvolvability, Constraints, Evolvability, Flexibility, Pc1Percent, Respondability.

Usage

MeanMatrixStatistics(cov.matrix, iterations = 1000, full.results = F,
  parallel = FALSE)

Arguments

cov.matrix

A covariance matrix

iterations

Number of random vectors to be used in calculating the stochastic statistics

full.results

If TRUE, full distribution of statistics will be returned.

parallel

if TRUE computations are done in parallel. Some foreach backend must be registered, like doParallel or doMC.

Value

• dist Full distribution of stochastic statistics, only if full.resuts == TRUE

  mean Mean value for all statistics
