We are seeking maths and stats problem solvers who can provide a simple formula, algorithm to calculate risk. The real data or problem cannot be shared publicly so we are providing a simple case for the freelancers to review and submit a one page solution describing their approach and the risk calculation. The freelancer providing the simplest solution will be chosen. Sample scenario: A company has 50 employees. The employees undergo a survey in which the company captures information about the employees such as age, gender, etc. The company has some jobs such as driving, transportation etc which requires workers to be comparatively less risky than others. A sample out put of the survey/survey fields are as follows: --- Name Age Gender --- Risk attributes 1. Smokes - ( risk scale 0-10). (S) 2. Drinks alcohol ( Risk scale 0-5) (A) 3. Gets traffic tickets ( Risk scale 0-100) (T) Based on the above, develop mathematical calculations where risk S,A,T representing Smoking,Alcohol and...

I need to have some simple code developed to run the simultaneous probit-tobit (SPT) model as described in page 77-78 of the attached document. I have access to R and MATLAB, so it would need to be in one of these two languages. I would like it to be developed in such a way that I can load the code and run the model with my data with ease. I would also like the code to be commented in order to explain what is happening with each line. Please feel free to contact me if you have any questions. I am happy to pay well for the right qualified person.

I need some help with Wavelet analysis in Matlab or R. This project will develop Matlab or R code to analyze Poisson distributed disease presence/absence time-series data with time-series weather data (precipitation, mean temperature). On completion of project any/all code will be transferred to client and its functions need to be demonstrated.

Coder must produce clean, well-documented code for two-class discriminant function analysis using leave one out cross validation and Mahalonobis distance with specific defaults. Language can be Python, R, C/C++ or Java. Code must be in shell script format to be called by a database platform. Implementing SPSS through Python is also possible and a big plus. If this project is successful, there will be many more statistical or machine learning procedures to be implemented. Familiarity with ODBC, Filemaker and Windows Server 2008 are preferred.
