A positively skewed distribution is one in which the tail of the distribution shifts towards the right, i.e., it has a tail on the positive direction of the curve. In mathematics, specifically advanced statistics, bimodal refers to a continuous probability distribution (a projected probability spread) over a graph that, when calculated with different mathematical modes, show different pattern spreads. Digital innovation projects look significantly different from traditional application development projects. Bimodal Histogram. Monamine Oxidase Inhibitors. For this reason, it is also called a right skewed distribution. The PRC encapsulates the dynamical response of a neural oscillator and, as a result, it is often used for predicting phase-locked modes in neural networks.
