Two dimensional distribution

Two dimensional distribution

1. Depending on the type of relationship, there may be: Unilateral casual dependence, Interdependence, Direct dependence, Concordance, Casual covariation

2. According to its variants of linear regression, exponential function or potential function. exponential function or potential function

3. When the type of relationship is not linear, namely the F(x) is not linear.

4. Two-dimensional distribution is divided into two columns in abscissa x and its corresponding ordinate Y

5. Linear dependence measures

   • The covariance of the units depends on the measurement of the variables
   • Linear correlation coefficient does not depends on the units of measurement is the linear correlation coefficient

6. Absence of relationship when F(x)=0

7. Correlation analysis. Statistical technique for measure the closeness of the linear relationship between two or more variables on an interval scale

8. Regression analysis. Statistical technique used to derive an equation that relates a criterion variable to one or more predictor variables.
