Is there an analytic approximation to the minimum function? The generalized mean, and softmax are probably something similar to what I am looking for, since this is for an applied work (modeling), and I wanted something that is hopefully not an eyesore(?) and can be extended to more than two arguments. |

Efficient sampling of a mixture model @RandomGuy, take a look at this handout: web.as.uky.edu/statistics/users/viele/sta695s02/rejimp/… |

Efficient sampling of a mixture model @RandomGuy, I have corrected my answer, hopefully the rejection sampling article should be clear. |

Efficient sampling of a mixture model @mjqxxxx, We need to have $2f-g \ge 0 $. Your example doesn't satisfy that. |

Efficient sampling of a mixture model Integrating both sides, I think you need $ \sum_i w_i - \sum_j w_j = 1$. But this doesn't guarantee that total $f_X(x)>0 \forall x$. We'll just assumethat this is true. |

Efficient sampling of a mixture model In the standard model, $\sum_i w_i = 1$, and $\int f_i(x) dx =1 \forall i$. What is the corresponding normalization in your model? |
