Bivariate Sampling Statistics This site is a part of the JavaScript E-labs learning objects for decision making. Other JavaScript in this series are categorized under different areas of applications in the MENU section on this page. Enter (by replacing) your up-to-42 two samples paired-data sets where measurements are made jointly on two random variables (X, Y) per subject, and then click the Calculate button. Blank boxes are not included in the calculations but zeros are. In entering your data to move from cell to cell in the data-matrix use the Tab key not arrow or enter keys. Risk Assessment Process: Clearly, different subjective probability models are plausible they can give quite different answers. Cov(X, Y) / Var (X) is called the beta of the random variable X with respect to Y. Given you wish to invest $12,000 over one period (with the same length of time), how do you invest for the optimal strategy? Using the JavaScript we obtain: Beta (Currencies) = -0.4578313, and Beta (Gold) = -1.9
Crypto Canon - Andreessen Horowitz Here’s a list — building on and including Chris’ last roundup — of crypto readings and resources. It’s organized from building blocks and basics; foundations (& history); and key concepts — followed by specific topics such as governance; privacy and security; scaling; consensus; cryptoeconomics and investing; fundraising and token distribution; decentralized exchanges; stablecoins; and cryptoeconomic primitives (crytocollectibles, curation markets, games). We also included a section with developer tutorials, practical guides, and maker stories — as well as other resources, such as newsletters and courses, at the end. We’ll soon be updating this regularly at crypto.a16z.com, for now we’ll keep it updated here. Building Blocks and Basics WTF is the blockchain? Ever wonder how bitcoin (and other cryptocurrencies) actually work? How the bitcoin protocol actually worksby Michael N How does Ethereum work, anyway?

Transparency International - The Global Anti-Corruption Coalition Estimating Option-Implied Probability Distributions for Asset Pricing After interpolation in (K, σ)-space, we obtain enough data points to estimate the implied strike price density functions at each expiry time. To do this we use a computational finance principle developed by Breeden and Litzenberger [4], which states that the probability density function f(K) of the value of an asset at time T is proportional to the second partial derivative of the asset call price C = C(K). We first transform the data to the original domain ((K, C)-space) for each expiry time using the blsprice function: T0 = unique(D.T); S = D.S(1); rf = D.rf(1); for k = 1:numel(T0) newC(:, k) = blsprice(S, fineK, rf, T0(k), sigmaCallSABR(:, k)); end Here, fineK is a vector defining the range of strike prices used for the interpolation and sigmaCallSABR is the matrix created using SABR interpolation in which the columns contain the interpolated volatility smiles for each expiry time We then compute the numerical partial derivatives with respect to the strike price.
Les Bullshit jobs sont -ils vraiment utiles ? — Article initialement publié le 6 septembre 2013 Dans un essai publié dans le magazine britannique de gauche radicale Strike!, David Graeber, anthropologue et figure de proue du mouvement Occupy Wall Street s’en prend à ce qu’il appelle les « bullshit jobs » — comprendre : les « jobs à la con ». Paru le 17 août dernier, le pamphlet de l’anthropologue américain n’a pas tardé à être commenté à tout va. Selon David Graeber, une vaste majorité de travailleurs de bureau sont, à notre époque, aliénés en étant soumis à des tâches « inutiles et vides de sens » tandis qu’ils ont pleinement conscience de ne produire qu’un apport « superficiel pour la société ». Citant Keynes, qui prédisait en 1930 que les avancées technologiques permettraient, d’ici la fin du XXe siècle, de réduire le temps de travail hebdomadaire à 15 heures par semaine, David Graeber souligne l’ironie de notre système économique. Des métiers dont la société se passerait sans problème Il n’y a pas que le travail qui compte
Eurostat Eurostat est une direction générale de la Commission européenne chargée de l'information statistique à l'échelle communautaire. Elle a pour rôle de produire les statistiques officielles de l'Union européenne, principalement en collectant, harmonisant et agrégeant les données publiées par les instituts nationaux de statistiques des pays membres de l'Union européenne, des pays candidats à l'adhésion et des pays de l'Association européenne de libre-échange. Historique[modifier | modifier le code] Eurostat a commencé à fonctionner en 1953 pour répondre aux besoins de la CECA : l'article 47 du traité autorisait la communauté à collecter des statistiques, indispensables à sa bonne marche. À partir de 1958, Eurostat devient l'un des trois services partagés par la CECA, la CEE et Euratom. Au début des années 2000, une polémique (en) a porté sur d'éventuels détournements de fonds. Rôle et activités[modifier | modifier le code] Eurostat fournit parfois des agrégats, par exemple:
