Linear Regression Calculator
‘Trend’ allows you to calculate unknown values of linear functions by interpolating the data mathematically, i.e., using the regression equation to calculate unknown values. This is more accurate than trying to visually read a graph whether it is hand-drawn or computer-generated, e.g., enter a set of sample absorbances and calculate the ...

determine if a linear regression model is adequate. determine how well the linear regression model predicts the response variable. Quality of Fitted Model. In the application of regression models, one objective is to obtain an equation that best describes the response data points . Consequently, we are faced with answering two basic questions.

regression equations. In this packet you will be calculating different regression equations. (Each problem will tell you which regression equation to calculate) Your calculator will find the equation for you. After we find the equation to represent the points (data), we need to know how well the equation matches the data.
