How to find regression line on ti 84
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 ...1. Exponential growth: Growth begins slowly and then accelerates rapidly without bound. 2. Exponential decay: Decay begins rapidly and then slows down to get closer and closer to zero. The equation of an exponential regression model takes the following form: y = abx. where: y: The response variable. x: The predictor variable.The following example will demonstrate how to calculate a cubic regression: • Press [home] and select List & Spreadsheet and press [enter]. • Input the data in Column A and Column B lists, pressing [enter] after each entry. • Press [tab] once to get to an empty cell. • Press the right arrow until you highlight 'x and press [tab].
