Solution 34423: ERROR: DOMAIN When Attempting a Statistical Regression on the TI-84 Plus C Silver Edition.
What does the ERROR: DOMAIN message mean when I perform a statistical regression on the TI-84 Plus C Silver Edition?
Statistical regressions include the following:• LinReg() - Linear Regression
• QuadReg() - Quadratic Regression
• CubicReg() - Cubic Regression
• QuartReg() - Quartic Regression
• LnReg() - Logarithmic Regression
• ExpReg() - Exponential Regression
• PwrReg() - Power Regression
• Logistic() - Logistic Regression
• SinReg() - Sinusoidal Regression
An ERR:DOMAIN will be displayed when performing a statistical regression where the data used does not fit the model for that particular regression. The error indicates that either:
a) There is an answer and it is out of the range of the calculator.
b) There is no solution for the problem.
Please see the TI-84 Plus C Silver Edition guidebook for additional information.
