Rebuild an Excel QMJ stock picking model in R

I have a QMJ stock picking model in Excel. This model is based on the paper added as attachment. What has to to be done: - verify the correctness of the implementation in Excel. Be critical on all aspects (data quality, mathematical correctness, optimization criterium, usage,...) - rebuild the model in RStudio, and explain potential discrepancies with the Excel model Key skills: - Excel - Rstudio - Portfolio management (understanding the attached paper is important) I'm flexible for the budget. It depends highly on the actual amount of workload, which is hard to predict in advance. Timing: - I'll take at least a few days/week to find the perfect candidate. - The data sets can only be deliverd on March 20. I'd like to have the project finished a few weeks afterwards.
