a) Perform Time Series Decomposition on your project Y variable excluding the hold out period. Show me the smoothed Trend Values, Smoothed Cycle Values and Seasonal Indexes.
b) Show the seasonal indices and develop a one year time series plot of them. Do they indicate strong seasonality? How can you tell?
c) Evaluate the "Goodness To Fit" usingRMSE and MAPEerror measures .
d) Evaluate the residuals for the "Fit" period byindicating the residual distribution (random or not). Use a fit period residual time series plot, residuals ACFs and a histogram to determine if the Fit period residuals are random. If the residuals are not random state if you detect anytrend, cycle and seasonality.
e) Develop a one year monthly or weekly forecast or a two year quarterly forecast (for the hold out period) using the time series decomposition model you evaluated in c) above.
f) Evaluate the "Accuracy" of the forecast for the "hold out period" using the RMSE and MAPE measures used in partb) and comment them. Did the error measures increase, remain the same or decrease from the "Fit" to "Hold Out" or forecastperiod?
The demand for lumber, like that for carpenters, is a derived demand-derived from lumber demand in its many uses, particularly housing. When the demand for new housing increases, so does the demand for lumber. For example, as the U.S. economy reco..
What is an "oligopoly" and why do they exist? Mention three or four oligopolies whose products you own or regularly purchase.
Analyze how inflation could occur in a society that relies exclusively on barter versus money. Speculate what form inflation would take and how you would recognize it. Provide support for your response.
Does the increase in the current price increase or decrease the asset’s average expected rate of return? At what price would the asset have a zero average expected rate of return?
Use arc-approximation formula to compute the price-elasticity of demand coefficient of the firm's product demand between the (quantity, price) points of (100, $20) and (300, $10).
Suppose instead that the goverment wished to raise GDP to 7,100, but it was unwilling to run a surplus or deficit. Therefore the change in government purchases would have to be matched by and equal change in taxes. What change in government purcha..
The presumption of efficiency for capitalism is based on the model of perfect competition. Explain the assumptions underlying the model of perfect competition. Provide an example showing how the US economy diverges from each of these assumptions.
Intermediate Microeconomics - Budget Constraint: Draw Alan's budget constraint with such promotional campaign.
Consider an electricity market with a daytime (peak-period) inverse demand of P=160-Q, and a nighttime (off-peak) inverse demand P=80-Q, where P is the price of electricity and Q is units of electricity.
Give two example of a negative externality and two examples of a positive externality Explain why market outcomes are inefficient in the presence of externalities.
College students sometimes work as summer interns for private firms or for the government. Many of these positions pay very little or nothing.what is the opportunity cost of taking such a job.
Using the results obtained above, derive a table for the long run costs of the various levels of production of sweaters (10, 20, 30, 40). The table should show: quantity, total cost, average cost and marginal cost.
