Are Meditative states distinguishable from the pre-meditative ones? A new alternative study

Analysis of the HRV signals towards classification of pre-meditative and meditative states has been widely accepted among the research communities. However, none of the existing methods used so far successfully classifies the meditative and pre-meditative states. In this article, we introduce a new...

Description
Summary:Analysis of the HRV signals towards classification of pre-meditative and meditative states has been widely accepted among the research communities. However, none of the existing methods used so far successfully classifies the meditative and pre-meditative states. In this article, we introduce a new approach, which is based on Similarity Index introduced by A.C.C. Yang et. al. The method calculates the rank for each word of length four and compares probability distributions between each pair of subjects (both in meditative and pre-meditative states) by using Q-Q plot. The Q-Q plots show same probability distribution for the meditative states and different probability distributions for the pre-meditative states. Thus Q-Q plots clearly distinguish the meditative states from the pre-meditative ones.
