Answer

Answer: C. They involve the use of expert judgment to develop forecasts.

Explanation: Time series forecast mostly involve the quantitative factors such as demand in the past periods. They use the historical data to derive the patterns to predict the future events or demands. The past values related to the variables are considered along with the forecast error to predict the future. In time series methods, the past events are tracked and the same pattern is expected to follow in the future. In time-series analysis, expert judgement will not be considered because it is more of subjective than to derive from the past.
