One-Variable Linear Regression Mathematical Model of Color Reading and Material Concentration Identification

摘要

This article first to average processing of measurement data, using EXCEL to draw the color readings and material concentration scatter diagram, using linear regression analysis method to determine concentrations of linear regression equation with color readings and material model. We use the least square method to obtain the regression equation, and analyze the model error by using total sum of squares, residual sum of squares, regression sum, and model error.
