Question

What is meant by the trend component of a time series? How is a linear trend different from a nonlinear trend? CO What is meant by the trend component of a time series? ary OA. The trend component represents changes in time-series data that are unpredictable and cannot be associated with a seasonal, cyclical, or random component. OB. The trend component is the long-term increase or decrease in a variable being measured over time. OC. The trend component is a wavelike pattern that is repeated throughout a time series and has a recurrence period of at most one year. D. The trend component is a wavelike pattern within the time series that repeats itself throughout the time series and has a recurrence period of more than one year.

Answer 1

Answer: A trend line is a line on a scatter plot, drawn near points, that approximates the association between the data sets.

Explanation:

2. The linear trend in precipitation is the dominant trend type. The nonlinear trends occur much less frequently and more widely scattered over the globe. However, the nonlinear trends are credible patterns of change in precipitation.

3. The trend is the component of a time series that represents variations of low frequency in a time series, the high and medium frequency fluctuations having been filtered out. This component can be viewed as those variations with a period longer than a chosen threshold
