It is impossible to calculate a Betta. A Betta is a fish.
beta dc= ic/ib!!
Nice
Ib =Ic /beta beta is the gain factor of the amp.
By the Huckel determinant

Multiply r by r? I'm not sure if I understand your question, but that's how you calculate r^2.
calculate the effective return (mean return minus the risk free rate) divided by the beta. the excel spreadsheet in the related link has an example.
Using Excel: plot the benchmark returns against the stock returns. add a linear trendline and display the equation Beta is the slope of the trendline. Examine the spreadsheet in the related link for a worked example
Beta Beta Beta was created in 1922.
Beta Beta Beta's motto is 'Blepein Basin Biou'.
Bipolar transistor current gain is also called "Beta," or the h-parameter "hfe." beta = current_out / current_in The beta of a BJT is mostly determined by the thickness of the Base region, and by the excess doping in the Emitter relative to the Base. A thin Base and a heavily-doped Emitter leads to a high value for current gain. In a BJT, beta = Ic / Ib In a FET, beta is usually taken as infinity, since no current flows in or out of the gate. Beta is an impirical number. It means nothing unless the Ic is known or the load. It can have a beta from 1000 to 10 it all depends on the load.
You need to use the variance and covariance functions in Excel 1. Calculate the covariance of the stock returns with respect to an index 2. Calculate the variance of the index 3. Divide the first number by the second. See the related link for a spreadsheet
