Homework Answers
When using auto regressive regression analysis to find a best-fitting line to a set of time series data with trend, we should use time period as the independent variable.
true
Time period is independent and Y value of the regression would be dependent

(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...

3. A regression analysis of a data set yielded the Least Squares regression line: y = 15.8 − 0.7 x. (a) What would be the estimated mean of Y when X = 9? (b) A student said: “ If we plug x = 10 in the equation of the regression line, then we get an estimate for the value of Y.” What is wrong with this statement? (c) By how much, and in what direction, would you expect Y to...

I have to submit a term paper which involves conducting a regression and correlation analysis on any topic of my choosing. The paper must be based on yearly data for any economic or business variable, for a period of at least 20 years. The following also must be included in the paper: • The term paper should distinguish between dependent and independent variables; determine the regression equation by the least squares method; plot the regression line on a scatter diagram;...
