the estimated model for stationarity. Question 3 A researcher is trying to determine the appropriate order of an ARMA model to describe some data‚ with 200 observations available. She has the following figures for the log of estimated residual variance (log(ˆ 2 )) for various candidate models. She has σ assumed that an order greater than (3‚3) should not be necessary to model the dynamics of the data. What is the “optimal” model order?

The Probability of On-Base Percentage Affecting Total Team Wins I. Abstract In the baseball world‚ On-Base Percentage is the key element to a team’s advancement to post-season play‚ because offensive domination is essential to the desired outcome‚ namely‚ winning. The following will describe the relationship between On-Base Percentage and the total amount of wins a Major League Baseball team receives using a linear regression model and other descriptive graphs. II. Introduction Essentially

Marked Problem Set 2 Dagoberto Gonzalez Paez Student ID --65824138 November 28‚ 2013 1. Suppose that you can trade a riskless asset that yields 5% and two risky assets A and B. The expected return of asset A is 8% and that of asset B is 11%‚ while the standard deviation of asset A is 14% and that of asset B is 23%. The covariance between assets A and B is ?0:0322. Solution . rA‚B= CovAR(A‚B) / [(σA)(σB)] = -0.0322 / (14%)(23%) rA‚B = -1 But when rA‚B = -1

Exploring the Stroop Effect by using numbers Abstract The purpose of this experiment is to study automatic processes by replicating the previously carried out Stroop effect by using numbers. This experiment was conducted by recruiting 8 participants (4 males and 4 females)‚ who are working in a head-office of Save the Children Organization in Yangon‚ selected by an opportunistic sample. Participants were presented with a Stroop-experiment-task sheet which consists of two parts which was the congruent

PDF and CDF) Two random variables X and Y have joint pdf: fX‚Y (x‚ y) = csin(x + y) 0 ≤ x ≤ π/2‚ 0 ≤ y ≤ π/2 (a) Find the value of the constant c. (b) Find the joint cdf of X and Y . (c) Find the marginal pdf’s of X and of Y . (d) Find the mean‚ variance‚ and covariance of X and Y . 4. (Uncorrelated vs. Independent) (a) We have seen that independence of two random variables X and Y implies that they are uncorrelated‚ but that the converse is not true. To see this‚ let Θ be uniformly distributed
