We have an application that generates a set of several statistics for every record in our sql database, and publishes them to that database every night. All of our applications are in ruby on rails. The dataset is pretty big.
We recently had our programmer add several new statistics to the set - but none of them work right, and it seems he has hit a wall. This job is to fix the stats! It is urgent we get these numbers generating accurately. The statistics involved are correlations, some ratios, and downside deviation - nothing too complex but also probably a step above your most basic stats like avg/max/min. This is very time sensitive and must be completed by the end of the day on Friday.
I am looking for an expert in statistics, sql, and ruby. This will be a fixed price job, and payment will be contingent upon accurate publication of the stats. If you are selected to interview, you will be provided with more detail and will be asked to submit your bid for the price of the project. If everything goes well, there is definitely potential you will be hired for additional projects in the future.
