Need Algorithm for Scoring Key: I/O provided

We need a scoring formula developed to properly evaluate (& weight) input values from over 70 samples to match its derived output data. We will provide the correct output data values. For each set of input values, there are 4 output values.

Because we are under a 3rd party contract, bidders must sign an NDA before receiving the actual problem. We used a linear regression model / least squares approach unsuccessfully. The correct scoring algorithm may involve a quadratic formula or something potentially much simpler.

The scoring algorithm can be written in PHP, or C (compiled). The program will take the input data values (<75 items/sample) from 70 total sample input sets, with item value ranges from 1 to 5 (low to high). The final solution desired will calculate each of the 4 output values within .25% (that's 1/4 of 1%) of the actual output values.

The final output we request will be: 1) a written summary of the formula(s) used, 2) potentially the scoring key(s), weights or contributions developed for each of the input values and 3) the software program which takes all of the input values (passed as an array or tab delimited string), and returns the 4 output values (the program will basically be a function).

If you have an advanced degree in applied mathematics or are a very smart mathematician, we welcome your bid to solve this problem.

## Deliverables

We need a scoring formula developed to properly evaluate (and weight) input values from over 70 samples to match corresponding output data. We will provide the correct output data values. For each set of input values, there are 4 output values.

Because we are contracted by a 3rd party to solve this problem, bidders must sign a non-disclosure agreement before reviewing the actual problem. We have already attempted to solve this problem (unsuccessfully) using a linear regression model / least squares approach. It is possible the correct scoring algorithm may involve use of the quadratic formula or something more involved. It is equally possible, the answer key is very simple or basic, not involving any advanced math.

The scoring key developed can be written in PHP or C (the final C program must be compiled cleanly). The program will take the input data values (<75 items/sample) from 70 total sample input sets, where each items value ranges from 1 to 5 (low to high). There are 4 output values derived from each set of input. The final solution desired will calculate the output within .25% (that's 1/4 of 1%) of the actual output values.

The final output we request will be: 1) a written summary of the formula(s) used, 2) potentially the scoring key(s), weights or contributions developed for each of the input values and 3) the software program which takes all of the input values (passed as an array or tab delimited string), and returns the 4 output values (the program will basically be a function).

Please list your history solving similar problems, any related experience in applied mathematics or past assignments that dealt with working with quadratic formula. Candidates who appear qualified will be asked to complete a confidentiality and non disclosure document before reviewing the actual test data.

Below is an overly-simplistic example showing hypothetical Input and Output data. The data is bogus, so don't expend any effort to mathematically correlate the input values to the output score - it is simply meant to provide you with an idea of the problem's structure. Real data will be provided to applicants after review of their background and ok'd.

INPUT: IMAGINATION = 4, ARTISTIC INTERESTS = 3, EMOTIONALITY = 4,

ADVENTUROUSNESS = 5, INTELLECT = 5, LIBERALISM = 3

OUTPUT: Openness Score (0 - [url removed, login to view]) = .75

If you have an advanced degree in applied mathematics or are an expert mathematician, we welcome your bid on this project. Good luck!
