Within the zoning code are required minimum setbacks. A variance is a waiver of a setback requirement or height restriction in the code. It allows the owner to build closer to the property line than the code allows. For example, in an R-1 single family single and duplex zoning district, the minimum setback requirement for the rear is 10 feet on each side.
(13.0 - 14.2) = - 1.2. 1.44. Variance then weights each squared deviation by its probability, giving us the following calculation: (0.1)*(3.24) + (0.3)*(0.64) + (0.3)*(0.04) + (0.3)*(1.44) =. Portfolio Variance. Now that we've gone over a simple example of how to calculate variance, let's look at portfolio variance.
