The regression output in Microsoft Excel is pretty standard and is chosen as a basis for illustrations and examples ( Quattro Pro and Lotus 1-2-3 use an almost identical format). CLASSIFICATION OF REGRESSION MODELS In a regression analysis we study the relationship, called the regression func...
The multiple linear regression estimates are computed by the StatCalc plug-in in Excel, as shown in table 2.2. Table 2.2 The equation for predicting efficiency is Y=13.182+0.5830.044+0.3290.057+0.1120.197 1X2X3X4X5X6X In Table 2.3, we use ten examples as validation data. Apply the pre...
Analysis of variance(ANOVA) is a statistical procedure that provides information on the explanatory power of a regression. The result of the ANOVA procedure are presented in an ANOVA table, which accompanies with the output of a multiple regression program. An example of a generic ANOVA table is...
We now need to tell Excel what we are looking for in the Vlookup wizard. Remember we have created a new column that represents the concatenation of the item name and item size. So we need to find the concatenation of the item and size when we search for the data. To add the concatena...
many functions in R to aid with robust regression. For example, you can perform robust regression with therlm( )function in theMASSpackage. John Fox's (who else?)Robust Regression provides a good starting overview. The UCLA Statistical Computing website hasRobust Regression Examples. Therobustpack...
Welcome to the course Data analysis: Multiple regression analysis using R. This course introduces the concept of regression using Sir Francis Galto n’s parent- child height data and then extends the concept to multiple regression using real examples. The course has an applied focus and makes mi...
There are many excellent examples of the application of predictive models in hydrology and water science (Xu 2022; Zhang et al. 2022; Zhu 2023; Guo 2024; Yin et al. 2023a, 2023b). These studies highlight that nonlinear regression models, functioning as white box models, enable researchers ...

Traditional single classifiers refer to theclassification algorithmestablished by mathematics, physics,statistics, and other methods, includinglinear discriminant analysis(LDA),logistic regression(LogR), K-nearest neighbor (KNN) andnaive Bayes(NB), and other typical algorithms. Among them, linear discrimina...
with only three presenting an unclear or low rating. The meta-analysis shows the effect of MF on endurance performance was on average slightly negative (g = − 0.32, [95% CI − 0.46; − 0.18],p < 0.001). The multiple meta-regression showed no significant influences ...
