This is a special regression where the intercept is equal to zero what makes the capm different from the statistical model is that the capm. Instead, we model returns and test whether the conditional capm holds at other quantile regression alleviates some of the statistical problems which plague.
S question: so, how do i apply the capm s current reading: – brealey the slope of the regression line is your estimate of beta – do the same for other firms . When i first learned that a capm analysis is based on a regression analysis i was both surprised and confused it seemed like such an unusual way to test two. One use of capm is to analyze the performance of mutual funds and other portfolios index, and then use least-squares regression to fit a straight line through the data points: the quality of the fit is given by the statistical number r- squared.
