Bivariate statistical measures regression and connection

Bivariate statistical measures regression and connection

1. classification

   • one-sided casual dependence
     • This relationship occurs when one of the variables influences another, but not the other way around.
   • interdependence
     • occurs when the influence between the two variables is reciprocal. it would be a case of bilateral dependency
   • indirect dependency
     • two variables can show a correlation through a third variable that influences them
   • agreement
     • they are presented in two independent variables to which the correlation that may exist is determined
   • chance covariation
     • when the correlation between the two variables is totally casual or accidental

2. regression analysis

   • studies the relationship between two quantitative variables
   • statistical technique used to derive an equation relating a criterion variable to one or more predictor variables
   • studies the strength of the association through a measure of association called the correlation coefficient

3. regression analysis model

   • statistical
     • allows the incorporation of a random component in the relationship
   • standardized
     • the slope B1 indicates if there is a relationship between two variables
   • deterministic
     • Under ideal conditions, the independent variable can be a mathematical function of the independent variables.

4. regression

   • simple linear regression
   • multiple regression
   • Logistic regression

5. correlation

   • linear correlation
   • direct correlation
   • inverse correlation
   • null correlation
