Distribution Models
Normal Distribution
Symmetric bell-shaped distribution, suitable for many natural phenomena.
Log-Normal Distribution
Right-skewed distribution, common in particle size analysis.
Weibull Distribution
Flexible distribution with adjustable shape and scale parameters.
Rosin-Rammler Distribution
Widely used in powder technology and comminution studies.
