About

This is a small CLI program used for evaluation of the Hurst's exponent of the time series from a CSV file.

Building

For building you will nead the following:

• C99 compiler;
• CMake.

If you already have both, to build you need firstly got to the project's root folder (the one in which this README file is located) and secondly execute the following commands in your terminal:

cmake -S . -B target
cmake --build target

If no errors where emitted, you should have a build program at ./target/hurst.

Running

The program has the following CLI interface:

hurst [options] <CSV filenames>

To evaluate the Hurst's exponent you need a CSV file containing a time series of measurements of some value with time stamp or without it.

If you have a CSV file of the following format:

Date	Value
1970-1-1 00:00:00	24.98
1970-1-2 00:00:00	13.37

then you need no options to pass to the program and you can simply run the following way:

hurst path/to/csv/file.csv

If your time series CSV file has some other format see Options section for more information on program's behaviour customization.
