Would it make sense to use a regression to calculate beta for returns on a foreign exchange currency (regressed on a market average of all currencies) would the beta make sense (why/why not). P-values and coefficients in regression analysis describe the nature of the relationships in your model learn how to interpret these statistics. This section reviews basic statistics we will go through most of this very fast r and basic regression: estimating a capm. The least squares regression line is the straight line -- yhat = bo +b1x that minimizes the sum of the squares of the vertical distances of the observed points from the line use: --you can use the regression line to predict the value of y for any value of x by substituting this x into the equation of the line.
