What is PointForm? Hum, quite a number of symbols reported by ?*Form are internal. I bet they are generated internally by built-ins for the front-end. |

Solve pair of recurrence relations @lip1, have you had any progress on this? |

Unique[] symbol not properly tracked @rojo, I believe you should say "symbols created with Unique" instead of variables. The oddity is that symbols created with Symbol still work. So I bet Dynamic does more than a simple syntactic (but at runtime) resolution of dependency. |

Unique[] symbol not properly tracked @rojo, see comment above. I dared to post this and my guess as to why as answer ;-) |

Coding mistake? @halirutan, I think you forgot to mention the all important missing pattern n_ in LHS. |

Unique[] symbol not properly tracked Not sure if ok, but I attempted this With[{z = Unique[]}, Dynamic[w, Initialization :> (w = z)]] and it prints $nnn and if you update $nnn that in other cell it gets updated. It seems you need an intermediate regular symbol (z) attached, which later gets discarded by the scoping construct. Is this an answer? |

Question on operator: // N @badb, just let me add a link to the official operator precedence documentation. And as for a quick guide this one. |

Given a time series of n samples with a known probability mass function, how can I predict the next sample? "The purpose of the tool is to identify samples that don't fit the assumption of the chosen probability distribution." Hum, I believe you can measure the distance between the expected distribution and the empirical distribution, but I don't think you can pinpoint/blame specific samples. |

Block attributes of Equal @Mr.Wizard see what will be my last update about Plus |

Block attributes of Equal @Mr.Wizard, see Update 2! I bet there is a negative answer to your question "How can I get true blocking of a symbol such that it behaves generically within a scoping construct?" - there is not such thing, even for user-defined symbols. |

Block attributes of Equal Apologies, you guys were right @Mr.Wizard, there are observable differences between built-in symbols in Block as opposed to user defined. I wonder if there are more than the ones mentioned, or even if Block cannot fully clear a symbol in all areas of the Mathematica kernel - regardless if it is built-in or user-defined. |

Block attributes of Equal I thought the point of your question was if Equal had special behaviour in Block, that's what I understood. I edited my answer to clarify this. Besides, I tried the code without the x_H case and it didn't work, so I disagree with the general unpacking behaviour mentioned. |

Mathematica returns fuzzy plot let us continue this discussion in chat |

Mathematica returns fuzzy plot So, likelihood is an internal definition? |

Mathematica returns fuzzy plot Maybe you should do ?likelihood and see what Mathematica currently has for it. But even with the two x and x_ definitions in there, Plot works. |

Mathematica returns fuzzy plot what do you mean "the problem remains"? with a proper pattern in the LHS it works for me... I also use version 8, although on Mac. |

Multiply (not divide!) Vectors in a List by Their Own Norm hum, @cosmic-strider, according to the wikipedia article for a complex-normal z, |z| follows the Rayleigh distribution and the argument is uniform in [-Pi,Pi]. If wikipedia is right, here you go, both are available in Mathematica and should't be hard :) |

Multiply (not divide!) Vectors in a List by Their Own Norm I wonder if you could do this by using another distribution in the first place, not the uniform distribution. |

How can I use “Save as (html)” and still render code as text? @VF1, that approach crashes consistently. The best I can do is to convert to HTML as mentioned in my first edit, but still the special characters are not properly mapped. |

How can I use “Save as (html)” and still render code as text? @VF1, hum, not exactly as I have more options to supply and was trying "HTML" instead "XHTML". I will give it another go. If it works will be more than happy to accept answer. Tnx |
