The Z-Score is negative when the data point is below the mean and positive when it's above the mean; a Z-Score of 0 means it's equal to the mean.To determine the Z-Score for each third-party rating of a company, we calculated the mean of the ratings across all companies evaluated by that third-party source. Can you confirm that this will only impact Java archive (.jar) files? Before including each third-party data point into our scoring equation, we had to standardize it so that it could be compared accurately with data points from other review sources. Anywhere that data passed inwards from the outside is processed, it could be logged, and anywhere it could be logged, the logger might be coded using Log4j, so the bug could be exploited internally, too.
