Overview

In this post, we will calculate Error density metrics. The project information, error distribution numbers, and the error weights can be found at:

Code Error Density(CED)

CED=

 

NCE = Number of Code and Testing errors

KLOC = Thousand Lines of Code.

The project numbers in the provided link are. Lookup Table 1 for the number of errors detected in the Code and Testing phases.
