Which two of the accompanying portray predisposition difference compromise among MC and TD?

?

A) The MC calculation decreases fluctuation by testing until the terminal state, prompting higher predisposition. ?

?

B) The MC calculation diminishes predisposition by testing until the terminal state, prompting higher fluctuation. ?

?

C) The TD calculation diminishes change by testing few time steps, prompting higher predisposition. ?

?

D) The TD calculation decreases predisposition by testing few a period steps, prompting higher difference. ?

Question 2) What is the contrast between on-arrangement and off-strategy learning? ?

?

A)On-strategy learning learns by assessing the consequences of a conduct strategy to perform strategy enhancement for an objective approach, though off-arrangement gains as a matter of fact by assessing an objective approach and performing strategy enhancement for the objective strategy. ?

?

b) On-strategy taking in gains for a fact by assessing an objective approach and performing strategy enhancement for the objective arrangement, though off-arrangement learning learns by assessing the aftereffects of a conduct strategy to perform strategy enhancement for an objective arrangement. ?

?

C) On-approach taking in gains for a fact by assessing an objective arrangement and performing strategy enhancement for the objective approach, though off-approach learning learns by assessing the objective strategy to perform strategy enhancement for a conduct strategy. ?

?

D) On-strategy taking in gains for a fact by assessing a conduct strategy and performing strategy enhancement for the objective arrangement, though off-approach learning learns by assessing the consequences of a conduct strategy to perform strategy enhancement for the conduct strategy. ?

?

B) Eligibility follows empower further investigation of the state space. ?

?

C) Eligibility follows dole out credit to activity. ?

?

PROBLEM 4 Covariance and Correlation Based on the following information, calculate the expected return and standard deviation of each of the following stocks. Assume each state of the economy is equally likely to happen. What are the covariance and correlation between the returns of the two stocks? State of Economy Return on Stock A Return on Stock B Bear .108 -.067 Normal .126 .113 Bull .064 .276 Question 1. Consider the Covariance and Correlation 'om a random sample of size n, from two random variables. How many statements are correct? 0 l 2 3 4 Statement A. Covariance and Correlation are statistical measures of the linear relationship between two variables. Statement E. Correlation can take on any value. Covariance ranges between minus one and plus one. Statement C. For a sample size of 11, Population Covariance is equal to Sample Covariance times ((nl )fn). Statement D. Covariance can be considered a relative measure of a linear relationship. Correlation can be considered an absolute measure of a linear relationship. Question 1 Covariance and Correlation The table below shows a set of sample bivariate data. Calculate the covariance and correlation coefficient by completing the below table. Show all working.
