I am working on a formula for a rating computation out of number of elements in 5 categories. The general idea is as follows: The possible number of elements for each category is different, and different should be the weight of influence for each of categories for the final outcome. In 4 categories the elements should have positive influence, and in on - negative. Name / allowed range of number of elements / weight of element influence / influence + or - Cat 1 / 0-20 / 1,5 / + Cat 2 / 0-20 / 1 / + Cat 3 / 0-5 / 3 / + Cat 4 / 0-5 / 5 / - Cat 5 / 0-20 / 0,5 / + Now: the assumption is that final rating was in range 1-5. If in data set will be: - only 5 elements in Cat 4, then final rating should be 1. - there will be no elements in any category, then final rating should be 3. - there will be only 5 elements in category 4 and 5 in category 3, then final rating should be 4. - only 5 elements in category 3, then final rating should be 4.5. - all elements will be in any categories, but in category 4 there will be no element, then final rating should be 5. I tried to use an online tool for Multiple Polynomial Regression: Regression Tools - Online Multiple Polynomial Regression But using the data below, the errors are very high (see attached image). What is the problem here, are there any inconsistencies in the data? 0 0 0 0 0 3 20 0 0 0 0 4 0 20 0 0 0 4 0 0 5 0 0 4.5 0 0 0 5 0 1 0 0 0 0 20 4 20 20 0 0 0 4.3 20 0 5 0 0 4.6 20 0 0 5 0 2 20 0 0 0 20 4.2 0 20 5 0 0 4.8 0 20 0 5 0 2.5 0 20 0 0 20 4.3 0 0 5 5 0 4 0 0 5 0 20 4.8 0 0 0 5 20 2 20 20 5 0 0 4.9 20 20 0 5 0 3 20 20 0 0 20 4.5 0 20 5 5 0 4.3 20 0 5 0 20 4.8 20 0 0 5 20 3 0 20 5 0 20 4.8 0 20 0 5 20 3.5 0 0 5 5 20 4.3 20 20 5 5 0 4.4 20 20 5 0 20 5 20 20 0 5 20 3.5 20 0 5 5 20 4.6 0 20 5 5 20 4.4 20 20 5 5 20 4.5 10 10 5 5 10 4 Last edited by skipjack; March 19th, 2017 at 04:05 PM.

I uploaded it to a different service and used TOR to check, it should be well readable now. https://s10.postimg.org/vxmv1hlqx/table_new.jpg
