As big data continues down its path of growth, there is no doubt that these innovative approaches  utilizing NoSQL database architecture and Hadoop software  will be central to allowing companies reach full potential with data.
This is a predictive confidence interval in the sense that if one uses a quantile range of 100p%, then on repeated applications of this computation, the future observation X n + 1 {\displaystyle X_{n+1}} will fall in the predicted interval 100p% of the time.
A seasonal pattern exists when a series is influenced by seasonal factors (e.g., the quarter of the year, the month, or day of the week). Seasonality is always of a fixed and known period. Hence, seasonal time series are sometimes called periodic time series. A cyclic pattern exists when data exhibit rises and falls that are not of fixed period. The duration of these fluctuations is usually of at least 2 years.
