The answer is option (A).
(a)Trend – In a trend analysis of time series the graph can fluctuate from upward to downward movement. For example let us consider, the yearly trend of a sweater company, during winter time there will be an upward trend due to rise in sales, but in summer time there will be an decrease in trend or downward trend due to decrease in sales.
14. Time series where a general upward or downward movement can be observed (or is present)...
The upward or downward movement that characterizes a time series over a period of time is referred to as _____________.
5. The components of time-series are: a. Trend, Seasonal, Movement, and Random b. Trend, Mobility, Cyclical, and Seasonal c. Trend, Seasonal, Cyclical, and Random d. Trend, Seasonal, Cyclical, and Perfection The mean absolute deviation measures the accuracy of a forecast by calculating.. a. the mid-point of absolute forecasting error per period of historical data. b. the average absolute forecasting error per period of historical data. c. the standard deviation of absolute forecasting error per period of historical data d. both...
(1) When analyzing data where a steady increase or decrease over time can be observed, which method of forecasting would best fit and would probably predict a similar increase or decrease? Select one: a. Modified Trend Method b. Weighted Series Method c. Moving Average Method d. Normal Curve Method e. Trend Analysis Method (2) If you graphed the data points in a particular time series and a relatively flat, horizontal pattern was observed, the method that should be used to...
Question 32 1 pts Sustained, long-term movement in the average demand in a time series data is called: Trend component O random variation O Non-repetitive components Cyclical component Seasonal component
136) Assuming all else equal, if a bank expects a bank run in the future: 136) A) there will be an upward movement along its demand curve for reserves. B) there will be a downward movement along its demand curve for reserves. C) its demand curve for reserves will shift to the right. D) its demand curve for reserves will shift to the left. 137) Which of the following will NOT cause a shift in the demand curve for reserves?...
Time series patterns that repeat themselves after a period of weeks or months are called: Select one: a. Irregular variations b. Cycles C. Random variations d. Seasonality e. Trend
The sample data x1,x2,...,xn sometimes represents a time series, where xt = the observed value of a response variable x at time t. Often the observed series shows a great deal of random variation, which makes it difficult to study longer-term behavior. In such situations, it is desirable to produce a smoothed version of the series. One technique for doing so involves exponential smoothing. The value of a smoothing constant α is chosen (0 < α < 1). Then with...
artifact is an upward and downward movement of the waveform and the isoelectric lines shift locations. a. Somatic tremor b. AC interference c. Interrupted baseline d. Wandering baseline artifact appears as jagged peaks with irregular height and spacing. a. Somatic tremor b. AC interference c. Interrupted baseline d. Wandering baseline artifact appears as series of small spikes that create a think looking tracing. a. Somatic tremor b. AC interference c. Interrupted baseline d. Wandering baseline 91. This artifact occurs when...
