How to check if my dataset is normally distributed? Also, what do you mean by programatically? In most environments there are functions (as in SAS, R, SPSS) or libraries (python, java) that have some kind of normality test implemented (eg en.wikipedia.org/wiki/Shapiro%E2%80%93Wilk_test) |

Derivative of a sequence Main question you should ask yourself here is "Why do I need to do this?", i.e. what would such a derrivative mean. |

Convergence of sum of independent random variables. ah, the distribution. Yes, I do. Thanks alot. |

Convergence of sum of independent random variables. How do you define $\hat \mu$ ? What does "Let $\mu_{m,n}$ the law of $\sum^m_{j=n+1}Xj$" mean? @DavideGiraudo |

How come $\frac{n!}{n_1!\cdot n_2!\cdot…\cdot n_k!}$ is always an integer? Since the formula is derrived as a number of distinguishable permutations then it certainly must be an integer. |

Find the laurent series Actually try going by the route given here: en.wikipedia.org/wiki/Laurent_series. Try doing some integrations, put some work in it. Tell us where the problem exactly lies, based on yourndifficulties. |

calculating points in specific distance from given point & direction first equation gives you a sphere with radius $r$ around $(x_1, y_1, z_1)$, the second one gives you a plane orthogonal to $(x, y, z)$ and going through $(x_1, y_1, z_1)$. The intersection of these two constraints is the searched circle. Solve second equation for one variable, put it into first equation. |

Simple question: Why does $E(|X|) < \infty$ imply $E(|X|I_{|X|>a} )$ tends to $0$ as $a$ tends to infinity improved formatting |
