Marketing Forecasting Report This week your task is to create a marketing forecasting report for your product. Your forecast should include charts and graphs showing projected success by regions, countries or demographics. Discuss how you developed the forecast and any other economic factors that could cause a variance. To assist with this challenging task find […]
Calculate the mean and variance of S(t) and of U(t), where (S(r)),>0 and (U(r)),>0 are the aggregate claim process and the surplus process of the described model.
PROMPT An insurance company has an initial surplus of 100 and premium loading factor of 20%. Assume that claims arrive according to a Poisson process with parameter A = 5 and the size of claims Xi are iid random variables with Xi ,-,, exp( 1-0). The time unit is 1 week. Assume that 1 month […]
Consider the limiter g(x) shown in the figure below (left). What is the pdf of the output variable Y = g(X) if the input variable is Gaussian with mean a/2 and variance 1.
Probability Consider the limiter g(x) shown in the figure below (left). What is the pdf of the output variable Y = g(X) if the input variable is Gaussian with mean a/2 and variance 1. Let X be a uniform r.v. over the interval (1, 3]. What is cdf and pdf of Y = 1/X? Consider […]
List the statistical notation and written explanations for the null and alternative hypotheses for the study. Describe the independent and dependent variables, their levels, operational definitions, and characteristics.
PSCase Study 2 The readings for this week focus on the concepts of dependent-samples t tests and repeated-measures ANOVAs. In this discussion we will apply those concepts to the analysis of a case study. Read the “ADHD Treatment” case study presented in Chapter 20 of the Online Statistics Education text. In the body of your […]
How does your evaluation of the variance due to this variable differ when you look at it in the hierarchical analysis compared with the way you look at it in the standard analysis?
Data Analysis Project for Multiple Regression Select four independent variables and one dependent variable of your choice. They should all be quantitative. For this multiple regression project “physics” is the dependent variable while “gender,” “iq,” “ei,” “vsat,” and “msat” as independent variables. Run a standard or simultaneous regression with this a set of variables from […]
What is the difference between interventional studies and observational studies?
A. Compose your answer in approximately minimum of 1 paragraph (130 words or more, 5-6 sentences) in EACH post. B. You are required to use 2 outside peer-reviewed resources with each post, with in text citations and references attached per post. Sources must be reputable and reliable. References must be published within the last 5-10 […]
Find the optimal contract designed by the principal, the total welfare (i.e., the total certainty equivalent wealth) generated by the optimal contract, and the expected utility (i.e., the certainty equivalent wealth) gained by each of the two parties. Provide detailed motivation and comments at all steps of your analytical answer.
1. Consider a principal-agent relationship where agent’s effort, e, is not observable by the Principal, and hence it is not contractible. Agent’s output, z, is however contractible. Agent’s output is linked to agent’s effort by the following relationship: z = e + x, where x is a stochastic noise with E(x) = 0 and Var(x) […]
