sample correlation coefficient meaning in Hindi

Examples

1. See sample correlation coefficient for additional details.
2. The sample correlation coefficient is written:
3. where is the sample correlation coefficient between and; and and are the sample standard deviation of and.
4. Thus, the sample correlation coefficient between the observed and fitted response values in the regression can be written ( calculation is under expectation, assumes Gaussian statistics)
5. Examples of variance-stabilizing transformations are the Fisher transformation for the sample correlation coefficient, the square root transformation or Anscombe transform for type-II error.
6. In other words, if linear regression is the appropriate model for a set of data points whose sample correlation coefficient is not perfect, then there is regression toward the mean.
