Method and apparatus for auto journaling of body states and providing derived physiological states utilizing physiological and/or contextual parameter

An apparatus for measuring a state parameter of an individual, comprising

• a processor;
• at least two sensors in electronic communication with said processor, at least one of said sensors being a physiological sensor;
• and
• a memory storing software executable by said processor, said software including instructions for:
• collecting a plurality of sensor signals from said at least two sensors;
• and
• utilizing a first set of signals based on one or more of said plurality of sensor signals in a first function, said first function determining how a second set of signals based on one or more of said plurality of sensor signals is utilized in one or more second functions, each of said one or more second functions having an output,
• wherein one or more of said outputs are used to predict said state parameter of said individual.
