Variance of the Hellings-Downs correlation
نویسندگان
چکیده
The Hellings-Down (HD) function describes gravitational-wave (GW) induced correlations in pulse arrival times from pulsar populations. author presents a thorough analytical treatment of the HD variance, demonstrating how cosmological vs. effects can be separated, and variance measurements provide unique insight on GW sources themselves.

Variance Dispersion and Correlation Swaps
In the recent years, banks have sold structured products such as Worst-of options, Everest and Himalayas, resulting in a short correlation exposure. They have hence become interested in offsetting part of this exposure, namely buying back correlation. Two ways have been proposed for such a strategy : either pure correlation swaps or dispersion trades, taking position in an index option and the ...
متن کاملConditional Distance Variance and Correlation
Recently a new dependence measure, the distance correlation, has been proposed to measure the dependence between continuous random variables. A nice property of this measure is that it can be consistently estimated with the empirical average of the products of certain distances between the sample points. Here we generalize this quantity to measure the conditional dependence between random varia...
متن کاملThe role of correlation in analysis of variance.
A test of the significance of a row or column agent in an analysis of variance may be expressed in the form of correlation between the agent and the variate. A test of the significance of interaction variance may be expressed in the form o f correlation between the agents. These expressions are principally of theoretical interest in that the degree of significance in an F test or the value of a...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
