whereas coefficients closer to 0 indicate a weaker or no correlation. However, the interpretation of a “strong” or “weak” correlation can vary depending on the field and the specific research question.

The result of the regression analysis is displayed. Interpretation: Regression Statistics: Regression statistics is an array of various parameters that describe how well the measured linear regression is. Multiple R is a correlation coefficient parameter that indicates the correlation between variables. Its...

· Kriging is to predict the spatial distribution y(x) by minimising the variance of the prediction error, where the prediction error is the difference between true y(x) and predicted y(x). Or equivalently, Gaussian processes are to achieve the same goal by maximum likelihood interpretation. ...
