Clone the repository

External libraries are included in this repository through submodules. In addition to cloning the repository, you therefore also need to initialise and update those modules:

git clone git@github.com:aykhuss/miho.git
cd miho
git submodule init
git submodule update

or just:

git clone --recurse-submodules git@github.com:aykhuss/miho.git

Install

We use CMake to build our project. On macOS using homebrew, install it like so: brew install cmake.

To build and install the project, run:

mkdir build
cd build
cmake ..
make
make install

that should create a bin folder containing the miho executable in the main project folder.

Usage

Run miho -h to get a help display.

• probability distribution: get the x-y value pairs for the PDF by adding --pdf anywhere before the model specification
• use the format string passed via --format 'the format string' to control the information you want and how it is displayed, e.g. by default the format is '{median} {dob68_low} {dob68_upp}'. The list of available placeholders are:
  • {median}: the median of the distribution
  • {dob68_low} & {dob68_upp}: the lower and upper edges of the 68% degree-of-belief interval
  • {dob95_low} & {dob95_upp}: the lower and upper edges of the 95% degree-of-belief interval
  • {mean}: the mean of the distribution
  • {stdev}: the standard deviation of the distribution
  • {norm}: the normalisation of the PDF (should be compatible with 1)

A step-by-step example is given here for the Drell-Yan cross section.
