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.
So the Weibull density function has a rich variety of shapes, depending on the shape parameter, and has the classic unimodal shape when \(k \gt 1 \). In the special distribution simulator, select the Weibull distribution. Vary the shape parameter and note the shape of the probability density function.For selected values of the shape parameter, run the simulation 1000 times and compare the empirical density function to the probability density function.ary the shape parameter and note the shape of the distribution and probability density functions. For selected values of the parameter, compute the median and the first and third quartiles. \(Z \) has reliability function \(G^c \) given by \[ G^c(t) = \exp(-t^k), \quad t \in [0, \infty) \].
