A scree plot confirmed the two-factor solution.
In order to establish the number of factors,we used the method for parallel analysis of the scree plot.
The scree plot of the PCA(Figure) shows the presence of four factors with eigenvalues.
The analysis resulted in five factors with eigenvalues greater than 1,also supported by the scree plot analysis.
Scree plot indicated that three factors should be retained, as shown in Figure 2.
An EFA model with eight factors was adjusted andonly the first factor presented an eigenvalue>1,confirmed in the Scree plot.
The scree plot technique was used to confirm the amount of factors to be extracted.
Table 3 presents the results of the exploratory factor analysis,considering the number of factors identified in the scree plot test.
When observing the scree plot, it was not possible to conclude with objectivity if the model should use three factors.
To determine the number of factors to be extracted, the researchers used the criteria of Kaiser Eigenvalue>1,Cattell Scree Plot and Horn Parallel Analysis.
In the scree plot analysis, it was observed that the tool could be divided into two or three dimensions.
We used the principal component analysis to extract factors,considering only those with eigenvalues greater than one, combined with scree plot.
For the final model, a scree plot was employed for factor selection, and three factors were retained.
With the resultof exploratory factor analysis, the authors selected the five most significant factors from the scree plot analysis and the total explained variance Figure 2.
Scree plot analysis was performed to verify the number of factors that could be extracted.
In view of the sample size,the convergence of the Scree Plot and the Kaiser criterion, this number of factors was maintained in the final analysis.
In the analysis of the principal components,the factors that obtained eigenvalues total variance explained for each factor greater than one were selected and interpreted in a scree plot.
After analysis and observation of the Scree Plot, it was possible to identify the proposed division of the items in four or five factors.
The definition of the number of patterns to be extracted was defined in three steps: Kaiser criterion(eigenvalue>1.0), scree plot, and the interpretation of the composition of the patterns17 17.
Cattell's scree plot analysis indicated that the factor structure was best described as having either two, three, or four factors.
X x1, x 2,…, x s, Y y1, y 2,…, y s, in which s is the maximum dimension,obtained through a scree plot, and? is the diagonal matrix, which?j elements are given by Equation 5.
In regard to the criterion scree plot, it generally results in more factors compared to the latent root criterion, which is not a feasible solution in this situation.
To define the number of factors extracted, the following were examined:eigenvalues superior to 1.0; Scree plot and whether the components represented at least 60% of the explained variance.
Despite these limitations, the scree plot observation method is the best option considering the Kaiser's criterion which tends to remove an excessive number of factors.
Application of MCA created a two dimensional graph,since the curve formed by the inertias in the scree plot was considerably higher in the first factor and intermediary in the second.
The graphical analysis of the scree plot, made through the principal components, indicates that the correlation matrix is factorizable, with KMO 0.81 and indication of up to 7 factors.
Next, those data were represented in a Euclidean space through a"correspondence map". The maximum dimension s was selected through a scree plot, a graph criterion often used in factor analysis.
The observation of the Scree Plot shows a clear division into three factors, which explain 63.80% of the variance, positioned before the inflection and tending to rectify from that point onwards.
After determining the baseline, dimensionality was assessed through exploratory factor analysis, for each dimension of the proposed scale,extracting the factors through main components analysis with the help of the scree plot analysis criterion.
Based on the scree plot, eigenvalues and considering interpretability of patterns, four factors should be retained, which, altogether, explained 36.4% of the consumption variability Table 2.
