The GLM model for 1 time interval. The transmission rate parameters depend on the number of infectious IN and CE calves (IIN and ICE, respectively) and/or on the amount of MAP in the environment caused by IN or CE shedding (EIN and ECE, respectively). E depends on MAP secretion in current time interval from the infectious calves (either IN or CE) and amount of MAP remaining in the environment from excretion by the infected calves on previous days (t-1) weighted by σ.
