Compute the exponential and adjusted exponential smoothing forecast and linear trend forecasting. Compare it by MAD and E.The Bayside Fountain Hotel is adjacent to County Coliseum, a 24,000-seat arena that is home to the city's professional basketball team and ice hockey teams that hosts a variety of concerts, trade shows, and conventions throughout the year.
