Variable General Info
Season total number of visitors to beaches ?Comment:To estimate total attendance at each beach for the whole summer season, other factors must be considered. Given the variability in weather conditions, we predicted a summer season by averaging results using four seasons of weather (2012-2015). The town of Barnstable starts collecting parking fees on Memorial Day weekend and stops by Labor Day weekend, and these holidays can fall on different days each year. Therefore, a summer season for Barnstable can vary by a couple of weeks, but on average, there are 107 beach days that make up a summer season. Using predicted visits within the four years, we calculated the average total visits for a single summer. This prediction process was simulated two thousand times, drawing from the distribution of coefficient estimates and random effects to account for uncertainty in our visitation model. |
