...on dist. (# of pumps is very often = 0) The slugs were observed during 12 time slots which are correlated in time as AR(1). The time slots are divided into two categories: Resting time slots (the first 10) Excited time slots (the last 2) I used model: ************pumps_ti = state_t + slugs_i + error_ti slugs and error are normaly distributed pumps_ti - # of pumps for i-th animal and t-th time slot x_t - order of the time slot (x_1 = 1, ..., x_12 = 12) state_t - state_t = 0 for resting time slots (t=1,...,10) state_t = 1 for excited time slots (t=11,12)...
