5) There are three securities in a portfolio. For each security, the geometric mean of rate of returns in ten years is shown in Table 1. The covariances between each security are shown in Table 2. It is assumed that no shortsales are allowed. Table 1. Geometric mean of rate of returns for each security Security C 7.20% Security A Security B Security |Geometric mean ī; 6.30% 9.70% Covariance Security A Security B Security C Table 2. Covariances between rate of returns of securities Security A Security B 0.027 Security C 0.018 - 0.009 0.041 0.041 0.008 0.018 -0.009 0.016 Set the quadratic program to minimize the portfolio risk.
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
