I have a database with some millions of records, and all records have data associated with the same 720 variables and also each record has two variables with value 1 or value 0. Find the best optimal intervals of each of the 720 variables that have a greater quantity of 1 of the first variable, and also the smallest quantity of 1 of the second variable, that is, the optimal interval with the greatest difference between the number of 1 of the first variable and the quantity of 1 of the second variable. And at the end, show the results of the analysis in a list, with the optimal interval of each of the 720 variables. But ordering the variables in order of greater difference. Please indicate what type of program or programming language we would use to make such calculations of the optimum intervals of each of the 720 variables, in an automatic way.

Hello. Let me reword your description to demonstrate my understanding of it: You have a matrix of data whose elements are either 0 or 1. The matrix is x-million rows by 720 columns. You want to start by forming all column 2-tuples (minus tuples where both elements are identical). There are 517,680 such tuples (it might suffice to look at the 258,840 pairs, but for now I'll keep it as tuples). Let's suppose that the columns (10 and 98) are such that compared to the other 517,679 tuples (10, 98) has the biggest difference between the number of 1s in column 10 vs. the number of 1s in column 98, e.g., maybe there are 1 million 1s in column 10 and only 15 1s in column 98, and that difference of 999,985 is the greatest difference among all tuples (there might be ties, but ignore that for the time being); also note this accounts for the comparison between (98, 10), which would be -999,985. Next, remove all tuples containing either column 10 or 98, and repeat the analysis until there are no more tuples. The result will be 360 pairs sorted in descending order using Cx-Cy of (Cx, Cy) as the sorting key. Here is the pseudo-code: 1) [Initialize] Set 'm' to the x-million by 720 matrix. 2) [Simplify] Count the number of 1s in each column and set 'a' to the result. 3) Form all 2-tuples of 'a'. We now have a set of (cx, cy). 4) Convert (cx, cy) into (cx-cy, cx, cy). 5) Set (t,u,v) to (cx-cy, cx, cy). ...no more chars left. Contact me for the rest. -Don

Data Description is quite unclear. But not the problem behind. Could you edit better? We are talking about a database with Millions of rows and 720 Columns where each column could assume a binary value and you are interested in the first and second column? Or is needed to make some work of data cleaning and data wrangling (pivot ecc...) Is a data sorting and filtering problem based on two filtering rules on the first and second variable. Pandas, a Python framework specifically designed for Financial Data Analyst will be the suitable solution. Easy, Understandable, Reliable Python Code and a jupyter notebook to explain all the work behind. 1Day Exploratory Data Analysis and Code Design 2Day Code Implementation and First Work Review 3Day Feedback Implementation
