Parámetro Regresión is a statistical technique utilizada en análisis de datos and aprendizaje automático to understand the relationship between a dependent variable and one or more independent variables. The primary goal of this method is to model the dependencies between these variables by estimating the parameters que define la ecuación de regresión.
In a typical regression model, the dependent variable (also known as the target variable) is predicted based on a linear or nonlinear combination of independent variables (the features). The relationship is expressed through a mathematical equation, where the parameters (coefficients) indicate the strength and direction of the relationship between the variables. For example, in a simple regresión lineal modelo, la ecuación puede representarse como:
Y = β0 + β1X1 + β2X2 + … + βnXn + ε
Aquí, Y is the predicted value, β0 is the intercept, β1, β2, …, βn are the parameters associated with each independent variable X1, X2, …, Xn, and ε es el término de error.
Parameter Regression can be applied in various contexts including finance, healthcare, marketing, and social sciences, allowing researchers and practitioners to make informed predictions and decisions based on empirical data. Advanced variations of regression, such as polynomial regression, regresión de cresta, and lasso regression, further enhance its capability to model complex relationships and manage issues like multicollinearity and overfitting.
