Описание тега mixture
In statistics a mixture distribution has samples drawn from multiple distributions differing in either their forms or the parameters,
Simulated distributions can be modeled as IID draws from a single distribution or they can be formed from random draws from more than one such distribution. The simplest form would be c*Norm(0,1) + (1-c)*Norm(0,2)
when c is a number in the (0,1) interval.
