Technically, Standard Deviation quantifies the degree to which individual Data Points deviate from the central tendency represented by the Mean. Mathematically, Standard Deviation is calculated by taking the square root of the Variance. Variance measures the average squared difference between each Data...
Correlation is a statistical term describing the degree to which two variables move in coordination with one another. If the two variables move in the same direction, then those variables are said to have a positive correlation. If they move in opposite directions, then they have a negative cor...
(1857-1936) was an English academic and prolific contributor to the fields of mathematics and statistics. He is credited as the principal founder of modern statistics and an advocate of eugenics. Aside from the eponymous coefficient, Pearson is known for the concepts of chi-squared test and p-...
Nor does the correlation coefficient show what proportion of the variation in the dependent variable is attributable to the independent variable. That's shown by thecoefficient of determination, also known as “R-squared,” which is simply the correlation coefficient squared. The correlation coefficient...
In a portfolio model that has more independent variables, adjusted R-squared will help determine how much of the correlation with the index is due to the addition of those variables. The adjusted R-squared compensates for the addition of variables and only increases if the new predictor enh...
