With measurement errors taken into account in the simultaneous fitting of the measurement and the new regression equations, estimation of is unbiased; hence it reflects the true relationship much better. Certainly, introducing latent factors in models is not a free lunch..
A function point is a unit of measurement to express the amount of business functionality an information system (as a product) provides to a user. Function points measure software size. The cost (in dollars or hours) of a single unit is calculated from past projects. As of 2013, there are several recognized standards and/or public specifications for sizing software based on Function Point. 1. ISO Standards. 1  COSMIC: ISO/IEC 19761:2011 Software engineering.
In software development, a breakpoint is an intentional stopping or pausing place in a program, put in place for debugging purposes. It is also sometimes simply referred to as a pause. More generally, a breakpoint is a means of acquiring knowledge about a program during its execution. During the interruption, the programmer inspects the test environment to find out whether the program is functioning as expected.
