    Describing patterns in time series data A time series is a set of values (y1,y2,y3... ... etc.) observed at times t1,t2,t3... ... A time series can be classified as having one or more of the following patterns: (1) trend (2) seasonal (3) cyclic (4) random View the video of patterns in pathways and answer the questions on time series data. Your questions and answers can bIn the following topics, we will first review techniques used to identify patterns in time series data (such as smoothing and curve fitting techniques and autocorrelations), then we will introduce a general class of models that can be used to represent time series data and generate predictions (autoregressive and moving average models). Finally, we will review some simple but commonly used modeling and forecasting techniques based on linear regression. For more information see the topics below.
