Assignment Instruction: Use Rstudio. Your homework should be submitted as an R Markdown file. Please submit the knitted .pdf (or .html) file along with the .Rmd代写 file. Please clearly label the questions in your responses and support your answers by textual explanations and the code you use to produce the result. Note that you cannot answer the questions by observing the data in the “Environment” section of RStudio or in Excel —-you must use coded commands.
Data In this analysis you will investigate two datasets. The first dataset is the Standard & Poor’s 500 financial index (SP500) measured on a weekly basis over the sampling period 01/01/1990-10/19/2017. The next dataset is the Dow Jones Industrial financial index (DJI) measured on a weekly basis over the sampling period 01/01/1990-10/20/2017.
Bootstrap Procedure, The Autoregressive Model, 代写Estimation
We consider the autoregressive lag 1 model stated below:
Tasks 1.Write a function that estimates the AR(1) parameter φ. Your function should use either the linear model function代写 lm() or the non-linear minimization function nlm() to estimate the parameter φ .To incorporate the bootstrap procedure for Task 2, your function should generalize to any data vector. Use your AR(1) function to estimate φ for both datasets “SP500Weekly.csv” and “DJIndustrialDaily.csv.” Note: to incorporate the bootstrap procedure, I recommend adding an additional argument in your estimation function that allows for the bootstrap indices.
2. Write another function that runs the bootstrap procedure on the parameter φ .This function should generalize to any dataset and should also incorporate the estimation function from Task 1. Set the seed to set.seed(0) and run B = 1000 bootstrap iterations. Please specify whether you used the percentile based bootstrap intervals or the regular bootstrap intervals. Test your function on the full datasets “SP500Weekly.csv” and “DJIndustrialDaily.csv.”
3. Run the bootstrap procedure on each dataset over the years 1990 through 2017. This will result in 28 intervals for each dataset. To summarize the results, plot the bootstrap intervals vertically as a function of time. Also plot a horizontal line at 1, which will indicate if the time series exhibits random walk behavior in in that year.
Ordinary differential equations describe the evolution of many phenomena in various fields, as we can see from the following four examples.
1. (Thermodynamics) Consider a body having internal temperature T which is set in an environment with constant temperature Te. Assume that its mass m is concentrated in a single point. Then the heat transfer between the body and the external environment can be described by the Stefan-Boltzmann law.
2. (Population dynamics) Consider a population of bacteria in a confined environment in which no more than B elements can coexist.
3. (Baseball trajectory) We want to simulate the trajectory of a ball from the pitcher to the catcher.
Application: pricing and hedging of Barrier options代写
Barrier option is a contract that pays to its holder a function of the terminal value of the underlying asset and of its maximum or minimum value.
Brownian motion accumulates quadratic variation at rate one per unit time.
Brownian Motion （BM）
BM is a martingale —Applications: ruin probabilities, first passage time BM is a strong Markov process Reflection principle —Applications Quadratic variation of BM
Martingales
Why martingales?
Usually expect (discounted) stock price process to be a submartingale. Reason: higher risk calls for higher returns (on average). Still, will think of (discounted) stock price as a martingale!
Stochastic Process and Markov Chains代写
For example, the price of a particular stock at the close of each day’s trading would be a stochastic process indexed by time. Of course, the index does not have to be time, it may be a spatial indicator. For example, the number of defects in speci ed regions of a computer chip. In fact, the indexing may be almost anything. Indeed, if we consider the index to be individuals, we can consider a random sample。
As with individual random variables, we shall be interested in the set S of values which the random variables may take on, but we shall generally refer to this set as the state space in this context. Again, as with single random variables, the state space may be either discrete or continuous. In addition, however, we must now also consider whether the index set T is discrete or continuous.
Markov Chain代写. The simplest sort of stochastic processes are of course those for which the random variables Xt are independent. However, the next simplest type of process, and the starting point for our journey through the theory of stochastic processes, is called a Markov chain.

Step #1: Data Cells Enter all of the data for the problem on the spreadsheet. Make consistent use of rows and columns. t is a good idea to color code these “data cells” (e.g., light blue).
Step #2: Changing Cells Add a cell in the spreadsheet for every decision that needs to be made. If you don’t have any particular initial values, just enter 0 in each. It is a good idea to color code these “changing cells” (e.g., yellow with border).
Step #3: Target Cell Develop an equation that defines the objective of the model. Typically this equation involves the data cells and the changing cells in order to determine a quantity of interest (e.g., total profit or total cost). It is a good idea to color code this cell (e.g., orange with heavy border).

PROJECT 1 – COMPANY VALUATION
Instructions for the Project
Students are required to develop a company valuation model using the discounted cashflow valuation and other methods for a company publicly listed on a stock exchange of a country of your choice (for example, the US, Japan, the UK, etc.). The company of your project requires the lecturer’s prior approval by the end of week 5. The model should contain:
Financial statements that are forecasted 5 years into the future based on the 5 years’ worth of past information provided. (Balance Sheet, Income Statement, Cashflow Statement)
Assumptions made in forecasting the future should be identified and justified withreference to past financial information, other annual report information and any other information sources that the student deems important
All assumptions made by the student should be reasonable andjustified
The model should also contain opportunities for the user to change key inputs to assess the impact on the firm’svalue
Students should feel free to add in additional information from the annual reports where it will add value to their model i.e. segmented revenue information or more detailed expense
The model should accurately compute the weighted average cost of capital and beta with the option of allowing users to alter the period and frequency of the beta used in the calculation of the WACC (i.e. one year daily data versus five yearsmonthly)
Accurately employ the Free Cashflows formula to compute the cashflows for the next 5 years based on the forecasted financial statements’ information, and then use the Discounted Cashflow and/or other methodologies to compute the value of the company and hence stock
Modelshould contain a summary page that brings together key inputs and key
The valuation model should conform to the rules of good financial model
The model will only be marked if it is built within the spreadsheet file 2020_V1_Valuation.xlsm available from Blackboard. Students are expected to be able toexplainordemonstrateanyfeaturesortechniquesintheirassignmentsifrequested.
–Model contains simple financial statements lacking in detail or that are exact copies of those provided by the company –Model contains suitable forecasting methods for most values –Weighted Average Cost of Capital is correctly calculated –Model correctly calculates the beta of the company
–Model correctly calculates the financial cashflows –Company Valuation is accurate given the inputs without excessive changes in values
Question 1 Goodnight Company manufactures beds. The company’s traditional management control systems have been criticised for concentrating on financial indicators. The Head of Performance Management wants an Integrated Performance Management System, which provides financial and non-financial aspects. The Balanced Score Card has been highlighted as a potential management tool that could be implemented.
