Exponential regression calculator.
Log Mode. Enabling log mode changes the strategy that the calculator uses to fit regression parameters. By default, regression parameters are chosen to minimize the sum of the squares of the differences between the data and the model predictions. When log mode is enabled, a transformation that makes the model linear is …

The exponential decay process can be expressed by the following formula: A(t) = A(0)e−rt. where A(t) and A(0) are amounts of some quantity at time t and 0 respectively, r is the decay rate and t is the time elapsed. The exponential decay is found in processes where amount of something decreases at a rate proportional to its current value.
