Between-group PCA performs a PCA on group means and projects the data points of the individuals on the resulting axes.
For example, the data points for 2008 represent the last year of the Bush administration, and the data points for 2009 represent the first year of the Obama administration.
The mean and standard deviation of the data points of the variables (Q, R and D) in each cell are used for computation of the CV in each cell based on Eq. (2).
The z-score coefficients of c are got in line 5; and at the moment, the data points of nc had not been determined yet.
Furthermore, in both cases (i.e., with and without ethanol addition), the data points of strain P are located at the bottom of the figure, while those of the evolved strains are located at the top.
The log V term in Equation (2) is constant across all possible segments and is computed once while reading the data points of 𝒫.
In the 'finite mixture model', an algorithm applying fixed residual variances is used for clustering of the data points of interest and subsequent estimation of the slopes of the linear regression lines.
First of all, the neighbors of each data point x i are obtained by calculating the Euclidean distances between neighbor points and the data point of interest.
This is an indication that, for each kind of process, the number, range and distribution of the data points in the operation region of interest are of paramount importance for proper training of the nonlinear model.
The SVM finds a separating hyperplane in the feature space between two classes in such a way that the distance between the hyperplane and the closest data points of each class is maximized.
