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;

    receive a calculated value that may be indicative of a physiological rate of the subject;

    generate a plurality of value pairs each comprising a first sample point of the physiological signal and a second point of the physiological signal spaced apart by a particular spacing, wherein the particular spacing is based on the calculated value;

    determine a best fit linear relationship based on the plurality of value pairs;

    determining at least one statistical metric based on the linear relationship and the plurality of value pairs; and

    qualify or disqualifying the calculated value based on the at least one statistical metric.
