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.
Since year-to-year variation on annual MWS is hard to predict, wind speed variations during a year can be well characterized in terms of a probability distribution function (pdf). This paper also addresses the relations among MWS, its standard deviation, and two important parameters of Weibull distribution.hen a location has c=6 the pdf under various values of k are shown in Fig. 1. A higher value of k such as 2.5 or 4 indicates that the variation of Mean Wind speed is small. A lower value of k such as 1.5 or 2 indicates a greater deviation away from Mean Wind speed.
