Regression A scatter plot (or scatter diagram) can be used to show the relationship between two numerical variables Correlation analysis is used to measure strength of the association (linear relationship) between two variables Correlation is only concerned with strength of the relationship No causal ...

The comparison of the prediction accuracy of the different modeling techniques using the Taylor diagram indicated that MLP-NN using LST, TWI, and elevation as inputs were more accurate in predicting the topsoil salinity [ECs (TS)] with a mean absolute error (MAE) of 0.43, root mean square ...
aOne-by-one approach andbonion approach. Both involve five training steps. The thicker line in each diagram shows one possible training sequence. For five datasets, each tree contains 120 (=5!) different branches and 325 (resp. 206) nodes in theone-by-one(resp.onion) approach. Each node ...
L1 regularizationadds an L1 penalty equal to theabsolute valueof the magnitude of coefficients. In other words, it limits the size of the coefficients. L1 can yield sparse models (i.e. models with few coefficients); Some coefficients can become zero and eliminated.Lasso regressionuses this metho...

Multiple linear regression analysis (Table3) indicated significant negative relationship between age and the RT tests (P < 0.01). Significant negative relationship was observed between RTclinand SES (P < 0.05). Significant negative relationship was found between PA and RTclinand RTV (P ...
