Predicted div yield next month

Using CRSP distributions, keep only distcd beginning in 12 and if the third digit of distcd is 3, 4, or 5. Also keep only if stock paid a dividend in the last 12 months. Define Ediv1 = div 2 months ago if distcd's 3rd digit is 0, 1, or 3. Define Ediv1 = div 5 months ago if the distcd 3rd digit is 4. Define Ediv = div 11 months ago if the distcd 3rd digit is 5. Define Edy1 as Ediv1/abs(prc). Finally, discretize Edy1 to smooth around the huge mass at 0 as follows: DivYieldST = 0 if Edy1 = 0, 1 if Edy is between 0 and 0.005, 2 if Edy1 is between 0.005 and 0.010, and 3 if Edy > 0.010.
