This singular historical and economic phenomenon is often associated with the ongoing decline in data processing and transport costs but, more than anything, it derives from "network effects": thanks to the extended arena of application of binary coding
, the usefulness of digital innovations (internet, search engines, mobile phones, electronic payment systems, TV, etc.
In regression analysis, dummy variables are usually introduced by using binary coding and the designation of a single reference group for the purpose of interpretation.
The binary interpretive framework uses binary coding and the omission of one category of the dummy variable.
JUNIOR maths boffins across Coventry have been getting stuck into binary coding
and 3D modelling to boost their brain power.
The traditional binary coding scheme is the starting point, and often the ending point, for the coding and interpretation of dummy variable coefficients for qualitative variables in regression analysis.
The specific information on coding the dummy variables is typically presented using a binary coding scheme (0,1).
The interpretive framework of dummy variable coefficients resulting for Shifting Processes I and II may also be obtained by using coding schemes that are alternatives to the binary coding scheme (Parker & Wrighton, 1975).
When using the binary coding scheme the reference category is always coded zero.
Output formatting is straight binary coding
with interface to either 3V or 5V logic.
