(USE ONLY EXCEL SHEET FOR DATA, FORMULAS, and the GRAPHS) For the following list of data (number of sold cars in every year), apply "exponential smoothing with trend" for all the years below. (i. e find the Forecast case1 use \alpha = 0.01 and \ including trend): beta = 0.3 - - - --- case2 use: for \alpha = 0.1 and \ beta = 0.05 Calculate MAD for both cases (5 %). . Decide which case values are better and why? (5 %) Assume trend is zero for the 2012 years. Year Number of sold cars 2012 107 2013 113 2014 150 2015 133 2016 151 2017 1 Based on least squared regression method find the projections for the years 2021, 2022, and 2023. Plot the number of sold cars versus years (points graph) and show the trend line based on your projections. (5%).
13.) The average temperature in March is 34 degrees, in April the average temperature is 43 degrees. What is the W_{0} increase from March to April?
Gold Tracker monitors the price of precious metals and has daily data on prices and sales of gold for the past several years. They estimated the following relationship (250 observations): Q=4,000-0.01P+1.5I-1.25X+2.0S R^2=.96 Q=daily sale of gold in ounces, P=price of gold per ounce, I= most recent inflation report (in percent), X= index of exchange rate, S is market price of silver per ounce. Standard errors are 857 for 4,000; 0.002 for 0.01P; 0.65 for 1.5I; 0.44 for 1.25X; 0.48 for 2.0S A. Evaluate the results of this regression. B. Recently, the price of gold has been $380 per ounce, inflation 0.2%, dollar trading at 99.7 on index, silver is $4.75 per ounce. What quantity of gold will trade on a daily basis? C. Are gold and silver substitutes or compliments?
Suppose a system is made up of seven components with iid lifetimes. The system will operate until one of the component fails. If the lifetime of each component is f(x)=3/x^4, x>1, what is the expected lifetime until failure of the system?
This list of largest cats shows the 10 largest extant Felidae species, ordered by maximum reported weight and size of wild individuals on record. a) Make a prediction what the relation between the maximum weight and maximum length should be. Give reasons why you are making such a prediction. (b) Draw a scatter plot, semilog plot, and log-log plot for these data and decide which model better fits the data. (c) From the graphs of (b), find a formula that expresses the relation between the maximum weight and maximum length of largest cats in better way (in your opinion). (d) Compare your prediction with the model that you obtained from the analysis of the graphs. Explain why your prediction is correct or why it is wrong. (e) Is there an outlier (or outliers) in the data that lies away? If yes, explain why it (or they) does not fit your model.
Suppose sales for the past 6 months have been94, 91, 102, 99, 109, and 118 Using a smoothing coefficient of 0.7, what is the exponentially smoothed value for the 4th period? (please round your answer to 1 decimal place)
A method of estimating earth temperature based on local precipitation is to build models based on 100s of years of earth at several different constant green house gas level (So constant global temperature for 100s of years) , and compare the correlation of statistical relationships between predicted precipitation patterns in a region, and observed precipitation patterns for a region in a few year time period.
Suppose sales for the past 6 months have been100, 90, 84, 113, 92, and 96 Using a smoothing coefficient of 0.5, what is the exponentially smoothed value for the 4th period? (please round your answer to 1 decimal place)
I have modeled adult worker's salaries based upon their work experience. After surveying 200 adults about their salary and years in the workforce, I have found the following model: y=12000+5000*x where y is the predicted salary and x is the years in the labor force. R^2 = 0.63. What is the correlation for this model? (correlation between salary and years in the labor force)? a. 0 b. 0.79 c. 0.63 d. 0.50 e. 1
Suppose sales for the past 6 months have been82, 104, 107, 116, 92, and 116 Using a smoothing coefficient of 0.5, what is the exponentially smoothed value for the 3rd period? (please round your answer to 1 decimal place)
