Representation of a real world situation.
The word “model” is used in many ways and means different things, depending on the discipline. For example a meteorologist might think of a global climate model, used for weather forecasting, while an agronomist might think of a crop simulation model, used to estimate crop growth and yields.
Statistical models form the bedrock of data analysis. A statistical model is a simple description of a process that may have given rise to observed data.
