correlationassociationCovariance is a measure of association, or covariability, between two variables (e.g., variables X and Y ). A positive covariance indicates positive association between X and Y , whereas a negative covariance indicates a negative association between X and Y . However, the magnitude of covariance is heavily dependent on the unit of measurement ...
We will use the Pearson Correlation Coefficient to determine the two assets’ correlation. This method, one of the most popular for measuring the linear relationship between two variables, will help us understand the relationship between two stocks: Facebook and Amazon, in our case. The average M...
In another post, I performed binary logisticregressionand obtained ORs for two continuous independent variables. Let’s interpret those odds ratios! In that post, I assess whether measures of conservativeness and establishmentarianism predict membership in the Freedom Caucus within the U.S. House of...
where x i and y i are ranks obtained for raw scores X i and Y i of variables X and Y . Apart from the performance evaluation, the experiments were also used for testing different aspects of the method itself, i.e. its sensibility to parameters and corpus. As mentioned, the method dep...
1. Large portfolios Calculation of Value at Risk for a portfolio not only requires one to calculate the risk and return of each asset but also the correlations between them. Thus, the greater the number or diversity of assets in a portfolio, the more difficult it is to calculate VaR. ...
A historical valuation uses a Fastmarkets time series to determine how much you could lose given a time horizon and a worst-case scenario range. Monte Carlo simulation uses the historical volatility of the time series and the correlation between multiple time series. ...
He suggested a nearly linear relation between BFOI and DO values. The relation, postulated by Kaiho29, is shown in Table 1. This implements a fixed BFOI value correlation to DO values after Kaiho29 like this: 100 BFOI = 6.0 [ml/l]; 50 BFOI = 3.0 [ml/l]; 0 BFOI = ...

The equation above reveals that the correlation between two variables is the covariance between both variables divided by the product of the standard deviation of the variables. While both measures reveal whether two variables are positively or inversely related, the correlation provides additional informa...
Like other aspects of statistical analysis, correlation can be misinterpreted. Small sample sizes may yield unreliable results, even if it appears as though correlation between two variables is strong. Alternatively, a small sample size may yield uncorrelated findings when the two variables are in fac...
