What is a parameter regression in modeling?

I tried googling it but in vain:(
Parameter regression modeling is a statistical method used to identify the relationship between a dependent variable and one or more independent variables. It involves estimating the values of the coefficients or parameters in a mathematical equation that best fit the data. It is commonly used to make predictions and understand the impact of different variables on the outcome.
The key components of parameter regression modeling are the dependent variable, independent variables, and the regression equation. The dependent variable is the outcome or response variable that is being predicted, while the independent variables are the variables that are thought to have an impact on the dependent variable. The regression equation is a mathematical formula that represents the relationship between the dependent and independent variables.
Parameter regression modeling is a type of linear regression, which means that the relationship between the dependent and independent variables is assumed to be linear. This is different from other types of regression, such as logistic regression, which is used for predicting binary outcomes, or polynomial regression, which allows for non-linear relationships between variables.
Parameter regression modeling is commonly used in various fields, including economics, finance, social sciences, and engineering. It can be used to analyze the impact of different factors on a specific outcome, make predictions, and identify trends and patterns in data. It is also frequently used in market research and sales forecasting.
While parameter regression modeling can be a powerful tool, it also has some limitations. It assumes a linear relationship between variables, which may not always be true in real-world situations. Additionally, it requires a large amount of data to accurately estimate the parameters, and it can be sensitive to outliers and influential data points. It is important to carefully consider these limitations when using parameter regression modeling for analysis or prediction.
