1. A subject monitoring system for processing physiological information of a subject, comprising:

  • a sensor configured to generate a physiological signal, wherein the sensor detects light attenuated by the subject; and

    processing equipment coupled to the sensor, wherein the processing equipment is configured to;

    select a first segment of the physiological signal comprising a plurality of values;

    select a second segment of the physiological signal comprising a plurality of values, wherein the second segment is shifted in time from the first segment;

    determine a correlation value between the first segment and the second segment;

    analyze the first segment and the second segment to determine a metric; and

    determine correlation information based on the correlation value and based on the metric.
