Unfortunately‚ this trend is not seen as an indication of higher quality or harder-working students. In fact‚ many studies have found that students in higher education devote considerably less time to studying and completing schoolwork than in the past.

An actuary uses a time series to estimate the average claim severity next year as $10‚000. We use this forecast to set rates for auto insurance policies. The procedure used to estimate the future average claim severity may be unbiased‚ bu the actual claim severity next year will not be exactly $10‚000. If the actuary’s estimate is a normal distribution with a mean of $10‚000 and a standard deviation of $500‚ we are 95% confident that the true average claim severity will lie between $9‚000 and $11

series models Time series is an ordered sequence of values of a variable at equally spaced time intervals. Time series occur frequently when looking at industrial data. The essential difference between modeling data via time series methods and the other methods is that Time series analysis accounts for the fact that data points taken over time may have an internal structure such as autocorrelation‚ trend or seasonal variation that should be accounted for. A Time-series model explains a variable
