Finding Equations
Does excel have a built in ability to view the equation/function to the
computations I am looking for? For example, I did a linear regression model and I get all these great statistics (T-stat, P-value, etc.). However, I want to know what their equations are. Does anyone have a suggestion? |

Finding Equations
There is only one or two equations but it doesn't describe the variables or
go into any details. Or did I miss something?

Finding Equations
Excel 2003 under regressionAbout statistical analysis tools
Excel 2007 under regressionPerform statistical and engineering analysis with the Analysis ToolPak You will find the various functions and the equations and logic behind most of them.

Finding Equations
Phosphide -
In general, I suggest using Google or some other search engine to get more information about regression equations. For simple regression, i.e., for one explanatory X variable, some functions are described in Excel's Help for "SLOPE function" and "INTERCEPT function." However, to avoid rounding errors and other problems, the methods used for computer computations may be different from the basic equation. For more information, consult the computer science areas usually called "numerical methods" or "numerical analysis." For multiple regression, i.e., more than one explanatory X variable, the "functions" are usually described using matrix algebra notation. Excel's Regression tool uses the LINEST function for many calculations. For information about Excel's LINEST function, see http://support.microsoft.com/kb/828533 - Mike http://www.MikeMiddleton.com "Phosphide" wrote in message ...
