👉 The term "coef" is a mathematical concept used in statistics and econometrics, specifically to refer to the coefficients of a model. In linear regression analysis, for example, the coefficients represent the slopes or intercepts of the line that best fits the data points. In other contexts, such as machine learning, the term can be used to denote the parameters or weights in a neural network or other statistical models, which are used to make predictions based on input features.
