Essays on I will provide the details shortly Coursework  Finance and Accounting work Question A) Individual hypothesis testing is the ability to test the given statistical hypothesis with the objective of accepting or rejecting a null hypothesis. On the other hand, joint hypothesis testing involves testing of the statistical method without giving a level of overall certainty of the fulfillment of the given objective. A given statistical phenomena can be fulfilled with respect to the method used.   B) The F test is based on the ratio of variances and is used to make comparison of two means or treatments. Therefore, the F test is used for experiments involving more than two treatments. Therefore, it determines whether one can assume that two independent estimates of variance can be assumed to estimate the same variance. The ability of the treatments to differ implies that the variation in treatment means will be greater than variation arising from random differences among individuals.   C) A single index model is a pricing model that measures that risk and the return on the stock of an organization with its common applications being in the financial industry. The multi-factor model also has its applications in the financial sector. However, the model involves utility of multiple factors in its computations that are used to explain the market phenomena such as equilibrium of prices. Its applications include explanation of individual or portfolio security. An example of a multifactor model is displayed below and is used to stock market factors.   Ri = ai + à ²i(m) Rm + à ²i(1)F1 + à ²i(2)F2 +â⬠¦+à ²i(N)FN + ei  Where:  Rià  represents the returns of security i  Rmà  represents the market return  F(1,2,3â⬠¦N) represents each of the factors used  à ²Ã  represents the beta with respect to each factor including the market (m)  eà  represents the error term  aà  represents the intercept  Question 2  a) t-values  ri = 0.080 + 0.801Si + 0.321MBi + 0.164PEi - 0.084BETAi   (0.064) (0.147) (0.136)	 (0.420)	 (0.120)   1.25 	5.45 	 2.36 	0.390 		-0.700  The t ratios are calculated by division of estimates by the standard error. Based on the provided estimates, and standard errors, the calculated t values are as indicated below each value in the above equation. The null hypothesis is rejected at the 5% level if the absolute value of the test statistic is greater than the critical value. The above values indicate that the absolute values are greater than the critical t values except for beta. This means that we reject the null hypothesis and confirm that the firm size and the market to book value have a significant impact in the returns of the stock of the firm.   b) The initial regression carried out is the unrestricted regression while the second is the restricted one. The F test is used to test the hypothesis with the sample values being:  F = [(RSSr ââ¬â RSSu)/m]/(RSSu/(n-k)  F = [(222.7 ââ¬â 203.8)/2]/(203.8/216-3-1) = 9.83  This is followed by calculation of the critical value of F from the tables at 5% level. The outcome is 3.00. The absolute value of F is higher than the critical value, thereby implying that we reject the null hypothesis and accept the alternative hypothesis that à ²2 and à ²3 are not jointly equal to zero. In addition, HML and SMB have a significant impact on the excess return of the portfolio of the company.   Question 3: The reported results indicate that there is evidence for the day-of-the-week effect. The outcome indicates that the day of the week effect has a positive impact on an individual due to the positive intercept. Similarly, Tuesday has a positive effect. However, the rest of the days of the week have a negative effect on an individual. Only the Monday dummy is significant at the 5% level of significance. This suggests that the Mondays returns are significantly smaller than Wednesdays returns on average (note that the coefficient is interpreted as the difference in average returns between Wednesday and Monday.  Exercise 5A: Lab Questions  1) a). The intercept is negative indicating that autonomous returns of all share FTSE is negative.   b). The slope coefficient beta is 1.408, which implies that the price of the stock is more volatile than the market. The stock price is 40.8% more volatile than the market.   c). The coefficient of determination R is 0.4874. This implies that the changes in the market explain 48.74% of the changes in the price of the stock.   d) In Q2, the p value is 0.0108. This means that there is relative evidence against the null hypothesis in favor of the alternative hypothesis. This is the reason for the rejection of the null hypothesis.   e) beta values are significant to the study and indicate that the stock price is highly volatile than the market.   f) the significance F is 1.3, which implies the variation among groups. This means that the null hypothesis is rejected.   5b   Q1, Q2, Q3  Prices  Log Returns  Date  PFT100  PBARC  RFT100  RBARC  Jan-2003  3567.4  240.63  à    à    Feb-2003  3655.6  260.69  0.02442

descriptive statistics  The means of RFT100 is higher than that of RBARC (0.0007). the standard error in RFT100 is 0.0036, which is lower than 0.012 of RBARC. The former has a higher median of 0.0098 compared to -0.0016. On the contrary, RBARC has a higher standard deviation of 0.1313 while its variance is 0.0172. RFT100 is skewed to the left at -0.8062 while RBARC is skewed to the right at 0.3187. Both have negative and positive minimums and maximums respectively while the sum varies.  7) Time series plot of prices
