$30-250 USD

Paid on delivery
Let x and y be normally distributed random variables, each with given mean and variance. Your task will be to derive the statistical distribution and some statistical parameters of z=min{x,y} from the CDF or PDF of x and y. The end result shall include: - Probability density function (PDF) of z in algebraic form, readily applicable in a standard graphing software - Expected value of z - Standard deviation or variance of z - Skewness (third standardized moment) of z - Kurtosis (fourth standardized moment) of z - Proofs of the PDF and above listed statistical parameters of z An approximation using Taylor series or similar is acceptable. Full payment will be made immediately after you sent the report in .pdf format.

I think it can be done using following trend: P(Z  z) = P(min (X; Y )  z) hint = P((X  z) [ (Y  z)) = = P(X  z) + P(Y  z)

What is meant by "Proofs of the PDF and above listed statistical parameters of z" (esp. in light of a Taylor series being acceptable)? My only access to produce a report in PDF format is via Mathematica's export utility, so really the report would be a Mathematica notebook exported in PDF format. I'm not sure whether that will suffice for your needs.

Dear client, I am Jack201307. Thank you very much for posting the project of “Derive Composite Statistical Distribution”. Though I successfully finished many statistical analysis and SAS Programming projects on other freelance websites, I may be not lucky enough on this website. Now good opportunity is coming, I can do this job definitely. For example, suppose X and Y are independent, cdf of X is f(x), and g(y) for Y, then cdf of Z is h(z)=P(Z< z)=1-P(Z>=z)=1-P(X>=z)*P(Y>=z)=1-(1-f(z))(1-g(z)). Partly, my experience, skills and knowledge include: * 10+ years’ experience with teaching various subjects, such as Statistics, Probability Theory, Advanced Algebra, Automatic Control Theory, Operational Research, Management Control System, System Modeling and Forecast, System Identification and Simulating, Adaptive Stochastic Approach, Marketing Research, etc. * Master Degree of Science in Applied Mathematics and Statistics (3 years) * Bachelor Degree of Science in Applied Mathematics (4 years) * 10+ years of experience with data manipulating, analyzing, mining and modeling. * familiar with many applications, such as MATLAB, SPSS, Visual Foxpro, MS Excel * SAS Certified both Base and Advanced Programmer for SAS 9 credentials, acquired in Toronto of Canada If you need more information about my qualifications, please contact me. Thank you very much for your time!
