Northeastern University Time Series Forecasting Project
The project consists of three parts. The submission of this project will consist of two attachments:1.A Word document that is prepared according to the APA standards of formatting. In the Word document, explain the experiments and their respective conclusions, and additional information as indicated in each problem
Either an Excel workbook or an R script file (.R file) that contains all the work and the calculations indicated in parts 1-3 of the project. Please save your Excel workbook or R script file
Part 1: Short-term Forecasting:
(i)Use a simple line plot of both time series to detect seasonal, irregular, or trend behaviors if any. Write a summary of your observations of both time series in your report.
(ii)Perform exponential smoothing to forecast both pricesfor period 253. Use successive values of 0.15, 0,35, 0.55, and 0.75for the smoothing parameter ?. Next, calculate the MAPD (Mean Absolute Percentage Deviation)of each forecast; and based on the MAPDs, determine the value of ?that has yielded the most accurate forecastfor each stock. In your report, describe your results; and explain whyin your opinionsuch valuesof ?haveyielded the most accurate forecasts for the two stocks.
(iii)Use your exponential smoothing forecast of part (ii) with ?=?.55and perform an adjusted exponential smoothing to forecast both prices for period 253. Use successive values of 0.15, 0.25, 0.45, and 0.85for the trend parameters?for both stocks. Next, calculatethe MAPEs(Mean Absolute Percentage Error) of your forecasts anddetermine the valuesof ?that haveprovided the most accurate forecasts for both stocks. In your report, describe your results and explain why, in your opinion,such valuesof ?have yielded the most accurate forecasts.
Part 2: Long-term Forecasting
(i)For each stock, use a 3-period weighted moving averages to forecast its value during periods 1 through 100. Use the weights 0.5(for the most recent period), 0.3 (for the period before the most recent), and 0.2 (for two periods ago). Next, use the observedvalue for period 101as the base of a linear trend, and use that linear trend to forecast the values of both stocks for periods 101 through 257. Write a summary of your results in your report. Describe how accurate this method of forecasting has been by comparing the forecasted values for periods 253-257 with their actual “Close”values on those specific days (Hint: check the actualvalues on https://finance.yahoo.com).
(ii)Calculate the MAPEs (Mean Absolute Percentage Error) of your forecasts in question (i) above andcompare them with the values obtained for your forecasts in Part 1.For each stock, describe which method has yielded a most accurate forecast.
Part 3: Regression:
(i)For each stock, use simple regression of stock values versus the time periods to predict its values for periods 1 through 257. In your report, describe how the accuracy of this prediction has been compared to the methods used in Parts 1 and 2 of this project
(ii)Perform a residual analysis of your simple regression to verify whether regression is appropriate to use for each of the given data. In particular, determine:
•Whether the residuals are independent
•Whether the residuals are homoscedastic
.•Whether the residuals are normally distributed by plotting a Normal probability plot of the residuals
•Whether the residuals are normally distributed by performing a Chi-squared test for Normality of the residuals
.After completing parts 1-3 and in your report, respond to the following question. Note this question is subjective, and it does not necessarily have only one correct answerat this stage of the course
.Question: Supposethat you have decided to form a portfolio ?(Pi)consisting of the above two stock types (denote a share value of AAPL by ?and that of HON by ?). You are however undecided as to what percentage of your investment should be allocated to the AAPL shares and what percentage should be allocated to HON shares. Let thesepercentages be denoted by P and Q respectively(Obviously, P + Q=100%). In your opinion, what are good values to select for P and Q

The Scenario:Frederick Jackson, one of the owners of Sports Gear, believes it is important to stress sports safety. He wants his sales associates to emphasize sports protective gear—such as helmets, padding, and cups—that is available in the retail store.For this assignment, you will need the following files:Sports_Gear protectionGear_PresentationYou will save your files as:Lastname_Firstname_Sports_GearLastname_Firstname_Gear_PresentationOpen the Sports_Gear_Protection file, and save it as Lastname_Firstname_Sports_GearIn the worksheet, adjust column widths so that all data displays.Apply a style to the titlesSet the titles to repeat on all printed pages.Create a chart on a new sheet.Format the chart, using a chart layout and chart style.Rename the sheets containing data.Insert the your name in the footer of all worksheets.Open the file Gear_Presentation, and save the presentation as Lastname_Firstname_Gear_PresentationApply a design theme and variant, and then add appropriate titles to the slides.On Slide 2, convert the bulleted list to a SmartArt object, and apply formatting.Insert a blank slide after Slide 2, and paste the Excel chart as a link.Insert a shape on one of the slides and modify the shape with at least two effects.Insert appropriate text in the shape and create a hyperlink to the Excel workbook.Add a slide transition to all slides.In the Excel worksheet, add a hyperlink to the presentation.In both files, add your name in the footer.

Capella University Capestra Furniture Order Entry Applications Program
Forms provide users with ways to interact with and input data. However, we also have other means to present the data in a format to help them with their daily activities: reports. Most reports will utilize a SQL SELECT statement or multiple statements to obtain the data for the output. It can be helpful to verify the SQL SELECT statement directly in MySQL Workbench before placing it in your code to ensure that it works correctly.In this assignment, you will create four reports and display them within the in the CapestraApp project. Each of the reports should run automatically or wait on a specific input before it is run. The report content can be created using the layout that you prefer, such as a TableView, or the information may be displayed in fields with labels; the specific design is up to you. Use the example report provided on the customer list as a starting point. Read the SRS for specific details regarding what is contained in each report and which user interactions (if any) are required.ResourcesClarification for Week 9 Deliverable [DOCX].Building Database Reports.Implementing Reports. | Transcript JavaFX TableView.Capestra Furniture SRS [DOCX].Reports: To-Do List [DOCX].Week 9 Sample Code [ZIP].Assignment InstructionsComplete the following steps for this assignment:1. Create each of these reports and display them within the in the CapestraApp projectEmployee Information: This report was provided within the CapestraApp template. Modify it so that it has a consistent appearance with the other reports that you create.Customer Information: This report should show complete details for a specific customer. The customer is selected using a drop-down (sorted by first name). As soon as a customer is selected, complete details regarding the selected customer are displayed below the drop-down. Order Information: This three-part report displays three tables:List of all customers.List showing details of all orders.List of all products and categories.Follow the example provided during this week to see roughly how the report might display and what code is necessary to create this report. Note that you cannot just copy and paste the example code: You should use it as a model for code that you write.Product Information: This report displays a list showing full details about all products in inventory including their names, descriptions, prices, categories, and quantities on hand.2. While your application is running, take screen shots of each report:Do not capture your entire desktop—just capture the individual screens.Paste all screen shots into a single MS Word document.Your name should appear at the top of the MS Word document.Name your document, following this pattern: Austin_Week9.docx.4. Create a .zip file containing your CapestraApp project.Before zipping your project, right-click the project and "clean" it. This greatly reduces the file size and speeds up the program's performance.Then close NetBeans.5. Add the MS Word document with your screenshots to your .zip file.6. Submit your cleaned CapestraApp project in an appropriately constructed and correctly named .zip file.Rename your .zip file, following this pattern: Austin_Week9.zip.
