1. A method of analyzing data, comprising:

  • a processor, of a computer system, receiving data corresponding to at least one time series; and

    the processor computing a plurality of sequential instability index values of the data from a corresponding plurality of sequential portions of the time series, wherein the instability index values correspond to at least one aspect of severity of at least one apnea or hypopnea cluster during the corresponding sequential portions of the time series;

    the processor generating a sequential and substantially real-time output of the sequential instability index values so that patient treatment can be quickly adjusted in response to the severity of apnea or hypopnea clusters.
