Crown gall causes stunting of growth. Both loss of yield and stunting of growth may occur when seedlings or young cuttings are infected in the early stages of plant growth. The lack of vigor, reduction in foliage, and water stress are associated with chronically diseased root systems.
1. In 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.
The following is a formal definition. Definition The probability density function of a continuous random variable is a function such thatfor any interval . The set of values for which is called the support of . Suppose a random variable has probability density function.
