GARCH processes are used to model the conditional volatility of financial returns in discrete time. There are many many different types of GARCH, the most popular and simplest being the GARCH(1,1), where returns have mean mu and conditional variance vt (t indexes time): returnt = mu + sqrt(vt)et where et is a standardized innovation.
Conditional variance follows a first order autoregressive process: vt= a + b* vt-1 + c* vt-1*et-1^2

What is a GARCH model?
A GARCH model is employed to help predict volatility (i.e. of stocks, XE rates etc) based on historical values through model fitting. Recent data is given more significance than older data. Compare to the least squares approach, which weights all the data equally. Since volatility is not the same across the entire data set (periods of volatility cluster together), this assumption is not valid. The related link provides greater detail and an Excel spreadsheet
What is reasonable accommodations?
A change in the work environment or in normal work processes that enables an individual with a disability to have equal employment opportunities
How does the NAICS work?
It groups establishments according to similarity in the processes used to produce services or goods
How does surface area work?
It would help if the question was less obscure. What do you mean by "work"? How the surface area affects chemical processes (for example the surface area of catalysts), or diffusion, or surface areas and friction?
Do top-down change plans work?
However, this strategy has proved to be largely ineffective in dealing with organizational change processes, particularly for successful integration.

What word do we apply to the concept that the processes that are at work on earth today are the same processes that shaped the early history of earth?
Geology
What summarizes how antibiotics work?
They interrupt processes vital to the bacteria.
What are Processes requiring energy called?
Processes requiring energy are called endergonic processes. These processes usually involve the absorption of energy from the surroundings to proceed. Examples include photosynthesis and protein synthesis.
How can you simulate GARCH process in Excel?
You need to set up an objective function via Maximum Likelihood Estimation, and then use Excel's Solver to maximize it for estimation parameters. Check out the attached link for an example Excel spreadsheet
What is the difference between competing processes and cooperating processes in operating system?
The difference is that competing processes in an operating system compete for resources. Cooperating processes share resources, and some even work together to complete the same task.
If you processes work together to form a cliff in the image below?
v
What is true of the processes that shape the Earth?
The processes that shape the Earth include plate tectonics, erosion, weathering, and volcanic activity. These processes work together to constantly change the Earth's surface over time.
What has the author Vernon L Stokes written?
Vernon L. Stokes has written: 'Manufacturing processes' -- subject(s): Manufacturing processes, Metal-work
What are the complex processes which work to break down the earth's surface called?
exogenous
