Creates an Object Representing Mixture Distribution
mixdist creates an object which represents the mixture distribution.
mixdist(..., weights) ## S3 method for class 'dist' mixdist(..., weights) ## Default S3 method: mixdist(dist, params, weights, ...)
... |
distribution objects. |
weights |
vector of weights for the components. |
dist |
vector of distribution names. |
params |
list of parameters for each component. |
A CDF of a mixture distribution function is
F(A)=∑ w_{i}F_{i}(A)
, where w_{i} is the weight of the i-th component and F_{i}() is the CDF of the i-th component.
The objects can be specified in two ways, either the user may enter distribution objects or a vector of names and list of parameters. See the examples below.
Object of class mixdist.
# using the objects
M <- mixdist(normdist(1, 3), expdist(4), weights = c(0.7, 0.3))
M
# using the names and parameters
M2 <- mixdist(c("norm", "exp"), list(c(mean = 1, sd = 3), c(rate = 4)),
weights = c(0.7, 0.3))
