using artificial neural networks (ANN) and multiple linear regression (MLR). Data of six variables, including areas, productivity zones, rainfalls, relative humidity, and minimum and maximum temperature, were c
Nonlinear regression model function, specified as a function handle.modelfunmust accept two input arguments, a coefficient vector and an arrayX—in that order—and return a vector of fitted response values. For example, to specify thehougennonlinear regression function, use the function handle@hougen...
normal prior on the SNP effect sizes and LD information from an external reference panel4. Consider the linear modely = Zβ + ε, where both the phenotypeyand the genotype matrixZhave been standardized. LDpred places an independent point-normal prior on each regression coefficientβj:...
Regression with the records having different weights. All of the other concepts in simple linear regression, such as fitting by least squares and the definition of fitted values and residuals, extend to the multiple linear regression setting. For example, the fitted values are given by: Y ^ i...
2005; Lee 2007) combining linear, quadratic or exponential costs. Also, the proposal of ROC space for regression (RROC) by Hernández-Orallo (2013) plots the total over-estimation and under-estimation error of models in X-axis and Y-axis, respectively. As in the context of classification, ...

(AI)-based models are becoming more popular due to their outstanding prediction results for multi-influential factors. In this study,support vector regression(SVR) techniques are adopted as the basic prediction tools, and five types of optimization algorithms, i.e. grid search (GS),grey wolf...
by the cyclones within a 30-year period. The wind and pressure from CFSv2 data were analyzed from 1979 to 2010 time span, with a time lag of 9 h identified for pressure and 26 h for wind stress. A multiple linear regression model was then employed to estimate the expected intensity of...
Answer to: The accuracy of prediction by the regression equation is enhanced by. (a) large samples \\ (b) a linear relationship \\ (c) both of the...
[12] used geometric features (extracted 18-dimensional ratio features from faces) and appearance features (40 Gabor feature maps) with shallow predictors, which are linear regression (LR), Gaussian regression (GR), and support vector regression (SVR). These methods were tested using the SCUT-FBP...
