This app employs Single Linear Correlation technics for univariate analysis and Principal Component Analysis (PCA) for multivariate exploratory analysis. The image data are acquired using the device main camera and converted in RGB histograms. In addition, apart color channels of RGB, HSV, HSL and HSI systems are used during the univariate and multivariate processes. It is possible to send by e-mail the image data, analysis data and charts. In order to validate the obtained results, the same sets of data were tested using Microsoft Excel© and ChemoStat©. The results in both applications coincided in various combinations.
This app calculates and plot: eigenvalues, eigenvectors, scores, loadings using Singular Value Decomposition in Multivariate Analysis.
This app calculates and plot: slope (span), intercept (off-set) and regression (Pearson product-moment correlation coefficient) in Univariate Calibration Analysis.
