1Measurement precision
If researchers use regression analysis to fit curve functions to dose-response data, then they can obtain parameter estimates, but the parameters may have high standard error and confidence interval values indicating unreliability
Solution Approach 1:
The patent introduces graphical indicators as intermediary visual elements between the raw parameter data and the researcher's interpretation. These indicators mediate the communication of parameter reliability by translating numerical confidence interval and standard error values into intuitive visual representations, enabling researchers to quickly assess parameter quality without deeply analyzing the underlying statistics
Solution Approach 2:
The patent employs color-coded graphical indicators to represent different levels of parameter reliability. By using color changes or color variations in the graphical indicators, the system provides an intuitive visual coding scheme where researchers can immediately distinguish between reliable and unreliable parameters through color perception, enhancing the communication of statistical confidence without requiring numerical literacy
2Productivity
If researchers focus on the curve fit function parameters, then they can perform data analysis, but they may fail to recognize the significance of high standard error and confidence interval values
Solution Approach 1:
The patent segments the parameter information into two distinct visual components: the parameter estimate value and the graphical indicator of reliability. This segmentation allows the curve fit function to be displayed with its parameters, while simultaneously presenting reliability information through separate graphical indicators, preventing the loss of reliability information while maintaining analysis efficiency
Solution Approach 2:
The patent adds a visual dimension to the traditional numerical parameter display by incorporating graphical indicators that represent reliability information. This dimensional enhancement transforms the one-dimensional numerical output into a two-dimensional visual representation that simultaneously conveys both parameter values and their reliability, making the significance of confidence intervals immediately apparent to researchers
