Linear, Logarithmic, Semi-Log Regression Calculator Linear regression is a type of statistical modeling that attempts to describe the relationship between an independent and dependent variable through use of a linear function. There are many well established methods for determining this linear function.

In summary, (1) X must be greater than zero. (2) The point (1, a) is on the graph of the model. (3) If b > 0, the model is increasing. Growth increases rapidly at first and then steadily slows over time. (4) If b < 0, the model is decreasing. Decay occurs rapidly at first and then steadily slows over time.
