The Exponential curve type could not be calculated for at least one location. The most common reasons for this curve type to fail to calculate are when the values of the Analysis Variable are nearly constant, contain negative values, or are nearly colinear (forming a straight line when plotted against time).
If Exponential was specified for the Curve Type parameter, all forecasts at these locations will be equal to the average (mean) value of the time steps. Features using a mean forecast will have the value mean in the Forecast Method field of the output features.
If Auto-Detect was specified for the Curve Type parameter, one of the other curve types will be used at these locations.
