Degree-based Statistics

Degree-based statistic for group network comparison and center persistency for brain connectivity analysis

Features

  • Perform a cluster-wise inference
  • Provide a corrected p-value in testing hypothesis of 2 sample t-test or Pearson's correlation analysis
  • New definition of a cluster which helps overcoming two innate drawbacks of cluster-wise correction
  • Robust parameter settings for spatial specificity & the arbitrariness of an initial cluster forming threshold
  • Provide an easily interpretable and statistically reliable result
