WebThe 95% prediction interval for the value at time 101 is 88 ± 2 (1.96), which is 84.08 to 91.96. We are therefore 95% confident that the observation at time 101 will be between 84.08 and 91.96. If we repeated this exact process many times, then 95% of the computed prediction intervals would contain the true value of x at time 101. WebTime series prediction is the task where the initial set of elements in a series is given and we have to predict the next few elements. These are significant as it can be used to predict video frames as well when provided with initial frames. Univariate time series data is a series where only a single parameter changes with time.
