Linear Trend Line Modeling a Nonlinear Trend • If the time series appears to be changing at an increasing rate over time, a logarithmic model in Y may work: ln(Y t) = a + b t + e t or Y t = exp{a + b t + e t } • In Excel, this is called an exponential model. where m = k is the slope of the line and b = log a is the intercept on the (log y)-axis, meaning where log x = 0, so, reversing the logs, a is the y value corresponding to x = 1. Trends indicate a slow change in the behavior of a variable in time, in its average over a long period.
