Exploring fit approaches for pressure calibration: An interactive web application for comparative analysis

In order to explain techniques for evaluating calibration data to determine the effective area and distortion coefficient of a pressure balance, we have created a user-friendly web application. With the help of this tool, users can investigate possible outlier or influential points, see the behaviour of scatter plots, and view regression residuals. It also makes it easier to compare different approaches to respective analysis: the weighted least squares model, the independent pressure model, and the ordinary least squares method. The software facilitates the comparison of models and the examination of the standard residual error that arises from every regression model. Moreover, an examination of the influence of outliers on the regression has been carried out, utilizing diagrams that illustrate the identification of outliers and the ensuing regression analysis in the absence of outliers.
