survive a Patrol Strike - Case Study ExampleHowever, linear regression requires that champion of the railroad cardinal variables be fixed, which is possible in the current scenario. The yellow line (for fines) is jolly easy to deal with. If we pass off the artificial blip of Christmas week and strike the clear outlier (Week 8) from the entropy, a trend appears. Smoothing would eliminate the faster lace up right before Christmas, as well as the blip for the week when there were no fines, because of no enforcement.Over time, the car-parks traffic appears to be continuing to rise, even figuring in the seasonal effects of the Christmas obtain rush. This increase is leading to significantly high revenues for parking fees in the weeks leading up to Christmas. However, both the higher alters in the weeks before Christmas and the lower results after Christmas do not suggest a business in trouble instead they suggest a business that is in a highly competitive indus analyze, urban c enter Centre Car-Parks market share appears to be growing, even if we smooth out the increases associated with the larger number of Christmastime shoppers.As will happen occasionally in the labor market, the staff who are creditworthy for operating the car park have threatened to walk off the job after week 23. Because this staff is responsible for making sure the self-pay machines are locked and for patrolling the lot and issuing fines, this could have a significant effect on the car-parks revenues. While it is likely that people would still pay the machines, the question of enforcement and collection would be a gluey one.It is possible to use time-series compend to figure out the approximate effect of such a walkout on the revenues of the car-park. The fundamental assumption of time series analysis is that the data being considered contain a domineering pattern, interrupted by error, or random noise, which can make the pattern difficult to find. Successful time-series analysis takes the random noise out of the situation as much as possible.The majority of time-series patterns consist of one of two basic types trend and seasonality. Trend refers to a linear or nonlinear component that undergoes change over time and does not repeat within the time utilized by the model. Seasonality is a little version of trend, because it represents a cycle that repeats itself within the time utilized by the model. A set of data may contain both trend of seasonality. A common example would be retail sales, which may grow from year to year but may also be easily predicted to spike more or less the Christmas season within each year (Time Series Analysis 2002).While there is no found or proven way to find trend components within a set of time-series data, trends are fairly simple to identify, as long as they consistently move in one direction or another. When a set of data is considered to contain a significant amount of error, though, the first step is to try a process ca lled smoothing.This consists of averaging data within the set with the goal of canceling out the individual data that do not fit within the existing system. The most common way that smoothing occurs involves moving average smoothing. In this technique, each item of data in a series is replaced by the simple or charge average of n surrounding pieces of data, where n is defined as the width of the window used for
