The Sum of Squared Residuals (SSR), also known as the Sum of Squared Errors (SSE), can be derived from the standard error of the estimate in the context of a regression model. Here’s how you can do it: Understanding the Concepts Relationship between SSR and Standard Error The standard error of the estimate (SE) is …
Degrees of freedom explained
Basic Concept In Different Contexts Why It Matters Simple Analogy Think of degrees of freedom as the number of choices you can freely make. Imagine you’re buying a set of colored pens, and the set must have 5 pens. If you choose 4 colors freely, the color of the 5th pen isn’t a free choice …
Pooling test & SSR
he term „pooling test” in statistics and econometrics usually refers to a specific kind of test used in the analysis of panel data or time series data. It’s designed to determine whether it is appropriate to pool data from different sources, time periods, or groups for joint analysis. This is particularly relevant in regression models …
Multicollinearity & VIF method
Multicollinearity refers to a situation in statistical modeling where two or more predictor variables in a multiple regression are highly correlated, meaning that one can be linearly predicted from the others with a substantial degree of accuracy. This can lead to problems in estimating the coefficients of the regression model, as it becomes difficult to …
What is complete mediation?
Complete mediation in the context of statistical analysis and regression models refers to a scenario where a mediating variable fully accounts for the relationship between an independent variable and a dependent variable. To clarify: In the case of complete mediation, the path between the independent variable and the dependent variable becomes non-significant when the mediator …
why Binomial Probit model is called like that?
he „Binomial Probit Model” is a type of regression used in statistics to model binary outcome variables. In this context: The model is specified as: In essence, the probit model calculates the z-score that corresponds to the probability of the binary outcome, and then uses this z-score in the linear regression equation. Just as with …
Why Binomial Logit model is called like that?
The term „Binomial Logit Model,” often referred to as logistic regression, is called so because it is used when the dependent variable is binary (binomial), meaning it has only two possible outcomes (0/1, Yes/No, True/False). „Logit” is a function that links the probability of the binary response to a linear combination of explanatory variables. Here …
