The first is to use the formula for beta which is calculated as the covariance between the return r a of the stock and the return r b of the index.
How do you calculate y hat. Regression is referred to as y-hat the letter y with a caret on top. To find your hat size take your ruler measurement and find the corresponding size on the chart. Y-hat is the symbol that represents the predicted equation for a line of best fit in linear regression.
Usually these charts will list the measurements in centimeters and inches. Written as x with a bar over it or x-bar. For 2 points r hat from point 1 to point 2 is given as such.
Calculate y-hat using the formula above and your given X value. Calculate p using the formula. Okay so do I not use.
