1. The Pearson Correlation By far the most common correlation is the Pearson correlation (or the Pearson productâmoment correlation) which measures the degree of straight-line relationship. D e f i n i t i o n The Pearson correlation measures the degree and the direction of the linearrelationship between two variables.
A core is usually the basic computation unit of the CPU-it can run a single program context (or multiple ones if it supports HW threads such as hyperthreading on intel CPUs), maintaining the correct program state, registers, and correct execution order, and performing the operations through ALUs.
Core i5. Developed and manufactured by Intel, the Core i5 is a computer processor, available as dual-core or quad-core. It can be used in both desktop and laptop computers, and is one of three types of processors in the i series (also called the Intel Core family of processors).he most common type of RAM used with a Core i5 processor is DDR3 1333 or DDR3 1600, however, higher performance RAM can be used as well (if the motherboard supports it). Power usage varies for the Core i5 processors: 1  Slower speeds (1.90 GHz to 2.30 GHz) use 11.5 W of power.
