Explained sum of square (ESS) or Regression sum of squares or Model sum of squares is a statistical quantity used in modeling of a process. ESS gives an estimate of how well a model explains the observed data for the process. It tells how much of the variation between observed data and predicted data is being explained by the model proposed.
What does a high ESS value mean?
The result of this comparison is given by ESS as per the following equation: ESS = total sum of squares – residual sum of squares As a generalization, a high ESS value signifies greater amount of variation being explained by the model, hence meaning a better model.

What are the flows in a warehouse?
There are three main types of warehouse layout flows that companies use to organize the way their warehouse operates: U-shaped, I-shaped, and L-shaped.

Thermal energy transfers occur in three ways: through conduction, convection, and radiation.
What is the purpose of transfer?
Transfer may be made to achieve the following objectives: To meet or fulfill organizational needs – To fulfill organisational needs arising out of change in technology, volume of production, production schedule, quality of product etc., an employee may have to be transferred.

The Problem
The short lifecycle of today's electronic products creates many pressures for rapid development and manufacture of new products, or product upgrades, in order to stay ahead in the competitive market place. Take for instance, the short model life of computers and printers. A new model appears every few months.
The ESS Solution
Environmental Stress Screening (ESS), is the solution. It typically utilizes thermal cycling with or without vibration to precipitate latent defects, the so-called "early life defects" which appear during the early life stage ofproduct use. The "bathtub curve" illustrates the life cycle of a product with early life and wear out defects.
HALT
The HALT test is utilized during product development. It determine initial weakness in the product by increasing stress level in steps to the component destruct levels. Then it replaces weak components with more rugged ones, thereby increasing product reliability.
HASS
The HASS process is a production screen to assure that weak components are precipitated (failed). HALT experience and the step stress empirical evaluation is used to establish a good screen. It is important that the level of stress is tailored to the product. There is no one-stress-fits-all.
