I am working on a project to forecast the arrival of patients to the emergency room within a specified time (future) period. Still consider myself a novice both in Rapidminer and data science but have a passion to learn. I ran into a technique called Unobserved Component Models (UCM) that seemed to handle (decompose) seasonalities, cycles, trends, etc. Intuitively there are "seasonal" factors like the day of the year, weekday / weekend, weather conditions, holiday / non holiday, etc.. that would be a factor on ER demand. When I searched in the operators in Rapidminer I didn't see UCM available. I didn't know if anyone had some suggestions, atlernatives, etc. Availalbe in R or Weka extension?
Appreciate any help.
