dMix: Mixture density

In anjaweigel/mixComp_package: Estimation of the Order of Finite Mixture Distributions

Description

Evaluate the (log) density function of a mixture specified as Mix object.

Usage

dMix(x, obj, log = FALSE)

Arguments

x	vector of quantiles.
obj	object of class Mix.
log	logical; if TRUE, probabilities/densities f are returned as log(f).

Value

dMix(x) returns the numeric vector of probability values f(x), logged if log is TRUE.

See Also

Mix for the construction of Mix objects, rMix for random number generation (and construction of an rMix object) and plot.Mix which makes use of dMix.

Examples

# define 'Mix' object
normLocMix <- Mix("norm", w = c(0.3, 0.4, 0.3), mean = c(10, 13, 17), sd = c(1, 1, 1))

# evaluate density at points x
x <- seq(7, 20, length = 501)
dens <- dMix(x, normLocMix)
plot(x, dens, type = "l")

# compare to plot.Mix
plot(normLocMix)
