Hi, Here's something I don't understand... How come that UNDEF can appear as a branch condition at all? I just can't think of any ways. If you write something like fun() { int x; if (x > 100) { ... } else { ... } } LLVM generates a boolean temporary that compares (uninitialized) value of x with 100. Second, if it already can appear, isn't that a bug that

...yle) It is not unusual for a well-designed experiment to analyze itself. Correlation may have nothing to do with causation: beware the lurking variables(s)! The idea of a process in a perfect state of control contravenes the second law of thermodynamics: thus a state of control is an unrealizable and must be regarded as a purely theoretical concept. The design of experiments was invented by R.A. Fisher to make it possible to conduct valid experiments in an environment (agricultural trials) that was never in a state of control. To find out what happens when you change something...

Dear list users, I need to learn about MCMC methods, and since there are several packages in R that deal with this subject, I want to use them. I want to buy a book (or more than one, if necessary) that satisfies the following requirements: - it teaches well MCMC methods; - it is easy to implement numerically the ideas of the book, and notation and concepts are similar to the corresponding R
