Model predicting the state of the lighting with the daylight illuminance level on the desk and occupancy.
In this model, the switching on action only happens upon arrival.
The probability to switch on the lights upon arrival would depend on the daylight illuminance level on the desk.
The model is documented in the paper "Love, J.A., 1998. Manual switching patterns in private offices. International journal of lighting research and technology, 30(1), pp.45-50."
The model parameters are regressed from observing the behavior of a 30 years old female without spectacles, who was located in a private office in Calgary, Canada.
The parameters recorded in the paper seem to be problematic and unable to reproduce the probability function illustrated in the paper.
