célváltozó

A "célváltozó" in statistical modeling, often translated as "target variable" or "dependent variable," is the variable that a model aims to predict or explain. It represents the outcome or phenomenon of interest that the researcher is trying to understand or forecast. In regression analysis, the célváltozó is the variable on the right side of the equation, whose values are determined by the predictor variables. For instance, if a model is built to predict house prices, the house price itself would be the célváltozó. In classification problems, the célváltozó is categorical, representing distinct classes or groups. An example would be predicting whether a customer will click on an advertisement (yes/no), where "click" or "no click" is the célváltozó. The selection and definition of the célváltozó are crucial steps in the modeling process, as they dictate the type of model that can be used and the nature of the insights that can be derived. The accuracy of a model is often evaluated based on how well it predicts or explains the célváltozó. The goal is to minimize the difference between the predicted values of the célváltozó and its actual observed values.
