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.
Probability distributions are a fundamental concept in statistics. They are used both on a theoretical level and a practical level. Some practical uses of probability distributions are: To calculate confidence intervals for parameters and to calculate critical regions for hypothesis tests.
