Correlations calculator

Calculates linear correlation between data ranges

Command-line options

corr-calc [DATA_FILE] [-o|--output OUTPUT_FILE]

• DATA_FILE -- input file. Default is "data.csv"
• OUTPUT_FILE -- output file. Defauilt is "results.csv"

Input format

CSV-file with each data-range as a row of the form:

%control-code%, %range-name%, %comma-separated doubles%

Ranges can have different sizes. In that case before calculating correlation between two ranges the longer one is truncated.

Example:

0, Range 1, 1.0, 2.5, 3, 4
1, Range 2, 1,2,3
2, Range 3, 0,9,8,7,6,5,4

Control code

corr-calc calculates correlations between rows using the following rule:

Calculate correlation between "Range 1" and "Range 2" iff control-code of "Range 1" is less than that of "Range 2"

Example

Suppose you have 5 ranges and you want to get correlations between

• range 1 and ranges 3 and 4
• range 2 and ranges 3 and 4
• range 3 and range 4
• range 5 and ranges 1,2,3,4

Resulting csv-file:

1, Range 1, ...
1, Range 2, ...
2, Range 3, ...
3, Range 4, ...
0, Range 5, ...
