WebbThe kernel plot represents the probability density function of the variable which helps us infer how the variable may be distributed in the population based on our sample. ... WebbIn probability theory, a probability density function (PDF), or density of a continuous random variable, is a function that describes the relative likelihood for this random variable to take on a given value. Probability density function is defined by following formula: P ( a ≤ X ≤ b) = ∫ a b f ( x) d x Where − [ a, b] = Interval in which x lies.
