The beta coefficient refers to the slope of the line, or rather the rate of change of y with respect to a change in x, assuming your function is. y = a + bx (b = beta) The beta coefficient has different implications in different fields, so if you are looking for a specific interpretation, please state.
To estimate beta, one needs a list of returns for the asset and returns for the index; these returns can be daily, weekly or any period. Then one uses standard formulas from linear regression. The slope of the fitted line from the linear least-squares calculation is the estimated Beta. The y-intercept is the alpha.
