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.
Density function. The form of the density function of the Weibull distribution changes drastically with the value of k. For 0 < k < 1, the density function tends to â as x approaches zero from above and is strictly decreasing. For k = 1, the density function tends to 1/Î» as x approaches zero from above and is strictly decreasing.
