STATISTICAL MODELS Meaning and
Definition
-
Statistical models refer to mathematical representations or frameworks for analyzing and interpreting data using statistical methods. They are used to understand relationships, patterns, and trends within datasets and to make predictions or draw inferences based on empirical evidence.
These models are constructed based on assumptions about the data generating process and seek to capture the underlying structure or fundamental characteristics of the variables under investigation. Statistical models are typically defined by a set of parameters that quantify different aspects of the data, such as mean, variance, or regression coefficients.
There are various types of statistical models, each serving a specific purpose. Descriptive models summarize and depict data distributions or patterns, providing insights into central tendency, variation, or skewness. Inferential models enable researchers to draw conclusions or make predictions about populations based on samples. Predictive models leverage historical data to forecast future outcomes or behavior. Explanatory models aim to unravel causal relationships between variables.
Model selection, estimation, and validation are essential steps in building statistical models. These involve choosing the appropriate model form or structure, estimating the model parameters using statistical techniques like maximum likelihood estimation, and assessing the model's adequacy and performance through various goodness-of-fit measures or hypothesis tests.
Overall, statistical models provide a powerful toolset for organizing and analyzing data, allowing researchers to describe, understand, and make informed decisions about complex phenomena, ranging from natural and social sciences to business and engineering applications.

Etymology of STATISTICAL MODELS
The word "statistical" is derived from the Latin word "statisticus", which means "of politics" or "pertaining to state affairs". This Latin term originated from the Italian word "statista", referring to a statesman or politician. The connection between politics and statistics arises from the historical use of statistics in understanding and managing societal affairs.
The word "model" originates from the Latin word "modellus", which means a small measure or standard for comparison. It is derived from the modern Latin term "modulus", meaning a small unit or measure. Over time, the term "model" came to be associated with representing or simulating a system or phenomenon, which helped shape the current usage in various fields of study.
When combined, the phrase "statistical models" refers to mathematical or empirical representations of phenomena in statistics.
