You can use a spreadsheet to calculate semivariance by setting up a column with all observed returns within a portfolio, sum the column and divide by the number of observations to get the mean. Next, remove all observations above the mean, and in another column subtract each remaining observation from the mean.
The semivariance at a distance d 0 will be zero, because there are no differences between points that are compared to themselves.
