## R Square

In statistics, the percentage of a portfolio's performance explainable by the performance of a benchmark index. The R square is measured on a scale of 0 to 100, with a measurement of 100 indicating that the portfolio's performance is entirely determined by the benchmark index, perhaps by containing securities only from that index. A low R square indicates that there is no significant relationship between the portfolio and the index. An R Square is also called the coefficient of determination. See also: Beta.

## R-squared.

R-squared is a statistical measurement that determines the proportion of a security's return, or the return on a specific portfolio of securities, that can be explained by variations in the stock market, as measured by a benchmark index.

For example, an r-squared of 0.08 shows that 80% of a security's return is the result of changes in the market -- specifically that 80% of its gains are due to market gains and 80% of its losses are due to market losses. The other 20% are the result of factors particular to the security itself.

Extensive work has been done on SPS using R-squared obtained from the regression of individual stock return to stock market returns (Morck, Yeung, & Yu, 2000; Durnev, Li, Morck, & Yeung, 2004; Farooq & Ahmed, 2014; Farooq & ElBannan, 2016).
The values of R-squared for the model are calculated as 0.

The comparison of adjusted R-squared of regression coefficient's first hypothesis was that the only difference in the dependent variables, indicates that the dependent variable NDNIj,t+1 is the coefficient of the highest value.
R-squared is a determination coefficient that represents the estimation of the total variation of the data described by the model.
We also note that the coefficient of determination, R-squared, increases dramatically from 0.
