What statistical technique would be appropriate for optimising the weights? To be honest, this may be something more appropriate for StackOverflow. |

How to search for a statistical procedure in R? +1: That's a really useful SO thread there. Pretty much reduces my question to a repost :P. |

Rigorous definition of an outlier? Not all outliers are generated from an experiment, however. I worked with a large dataset that involved the collection of real-estate information in a region (sale price, number of bedrooms, square footage, etc), and every now and then, there would be data entry mistakes and I'd have a 400,000 bedroom house go for 4 dollars, or something nonsensical like that. I would think that part of the goal of determining an outlier is to see whether it's possible to be generated from the data, or if it was just an entry error. |

How do I know which method of parameter estimation to choose? Onestop: This is certainly the spirit of the question I was aiming for. And thank you for the clarification between criteria of evaluating estimators and methods for deriving them! |

What are the breakthroughs in Statistics of the past 15 years? It's subjective, sure, but isn't it still okay for CW? |

How to use Confidence Intervals to find the true mean within a percentage That continuous result should be squared. $\sqrt{n}=\frac{Z_{c}\sigma}{E}$, and thus $n=(\frac{Z_{c}\sigma}{E})^2$ |

Consequence of violating independence assumption of ANOVA This does not directly pertain to the violation of independence, but have you considered multiple imputation to deal with your missing values? |

Predicting number of events with 99.9% probability based on tests of four devices The traditional way you could do this is through hypothesis testing. This will allow you to test whether the plausibility that the lifetime is equal to some value, say 10,000 times. en.wikipedia.org/wiki/Statistical_hypothesis_testing |

Proving that the squares of normal rv's is Chi-square distributed Thanks, mpiktas. I figured there must've been a mistake somewhere in my pdf. |
