- MARKET CAPITALIZATION is taken as a variable to be predicted, the rest are the predictors Create the following variables in the excel sheet: 1. Change Total Assets to ‘Log(Total Assets)-LogTA, 2. create a new variable called CR (CR= current assets/current liabilities), 3. Create a new variable called DR (DR= Total Debt/Total Asset), 4. Change Market Capitalization to Log(Market Capitalization)-LogMCAP Focus on LogMCAP, LogTA, CR, DR, EBIT, LogMCAP to be predicted, the rest are predictors for the purpose of completing the assignment. 1. Perform a descriptive analysis in R , using the variables given . 2. Design a structure to show the training data, testing data, and discuss the validation process using your dataset. 3. Perform a regression analysis, show the clearly and discuss on the predictive power using the forecast figures and coefficients. 4. You may include scatter plots to address the significance of the predictors, OR extend your analysis by using other statistical…Consider a simple model to explain a country’s alcohol related automobiles incidents (totaai) in terms of police police officers (topps): Estimating (a) using quarterly data from 1991-2024 gives: log(totaait) = 12.58 − 0.66 log(topps); (2.22) (0.33) n = 95; R2 = :439; 2. Test the null hypothesis that the coefficient on the log(topps) has no effect on the log(totaait) at the 5% level. 3. Suppose that both total alcohol incidents (totaai) and total police officers (totts) have a positive trend. Given this information, discuss whether the OLS estimates of ˛1 from equation (a) is unbiased (i.e., E(˛ˆ 1) = ˛1)?It has been noted that the amount of time people spend shopping in supermarkets has decreased due to the global pandemic.

- What if the model is a conditional logistic model? Will the answer be anything different? Thank you.A psychologist conducted a study to examine the nature of the relation, if any, between an employee’s emotional stability and the employee’s ability to perform in a task group. Emotional stability was measured by a written test for which the higher the score, the greater the emotional stability. Ability to perform in a task group was evaluated by the supervisor. An employee was given a 1 if they were able to perform a task in the group, and 0 if they were unable. Following output gives the results from a logistic regression analysis on the data provided by a sample of 27 employees. (a) what is the estimated logistic regression line? (b) Convert your slope estimate into an estimate for the odds ratio, and interpret the results. (c) Estimate the odds of the being able to perform in a task group for an employee with an emotional stability score of 510.I need help with this discrete mathematics problem involving a logarithmic function
- Who is the inventor of the logistic function? 1.Ludwig Ogistic 2.The iranian physicist Piver Verfraco 3.The Belgian mathematician Pierre François Verhulst.The prices of stocks or other financial instruments are often modeled with a lognormal distribution. An investor is considering purchasing stock in one of two companies, A or B. The price of a share of stock today is $1 for both companies. For company A, the value of the stock one year from now is modeled as lognormal with parameters μ = 0.05 and σ = 0.1. For company B, the value of the stock one year from now is modeled as lognormal with parameters μ = 0.02 and σ = 0.2. a) Find the mean of the price of one share of company A one year from now. b) Find the probability that the price of one share of company A one year from now will be greater than $1.20. c) Find the mean of the price of one share of company B one year from now. d) Find the probability that the price of one share of company B one year from now will be greater than $1.20.
