Skew multimodal normal distribution
In this paper the multimodal normal distribution is introduced. This distribution is a generalization of the standard normal distribution and covers the symmetric distributions with up to three modes. Then the skew multimodal normal distribution is introduced as a skewed-symmetric distribution generated by the standard normal distribution. Some properties of this distribution are investigated. Data generation methods from this distribution are proposed and its location and scale distribution is introduced. The maximum likelihood estimates of the parameters are studied and evaluated using simulations. The famous geyser dataset is fitted to this distribution and compared with several competing distributions.
