This project is for the paper submitted to Entropy journal entitled Composition Classification of Ultra-High EnergyCosmic Rays, it performs variable selection and model design to classify (multi-class) the type of particle in an event of UHECR.
Original data includes the following variables:
1 NALLParticlesTotal: number of particles generated at ground level
2 MUTotal: number of muons
3 ELTOTAL: Number of em particles
4 X_max: g/cm^2 Point in the atmosphere where the particle generates maximum number of interactions
5 Zenith: Zenith angle of the particle in degrees
6 Energy: Particle energy in GeV
7 Zfirst : Altitude of the particle's first interaction
