operators-methods: Methods for operators +,-,*,/,... in Package distr
Description
Arithmetics and unary mathematical transformations for distributions
Arguments
e1,e2
objects of class "UnivariateDistribution" (or subclasses) or "numeric"
concept
convolution
FFT
affine linear
image distribution
Details
Arithmetics as well as all functions from group Math, see Math
are provided for distributions; wherever possible exact expressions are used; else
random variables are generated according to this transformation and subsequently the remaining
slots filled by RtoDPQ, RtoDPQ.d
N <- Norm(0,3)
P <- Pois(4)
a <- 3
N + a
N + P
N - a
## don't run: to reduce check time on CRANa * N
a * P
N / a + sin( a * P - N)
N * P
N / N
N ^ P
1.2 ^ N
abs(N) ^ 1.3
