Description |
Linear
|
Calculates the least squares fit for the line y = m * x + b.
|
Logarithmic
|
Calculates a least squares fit for the logarithmic curve y = a * ln(x) + b, where ln is the natural logarithm.
|
Exponential
|
Calculates the least squares fit for the exponential curve y = a * b^x.
|
MovingAverage
|
Uses a sequence of averages calculated across each set of N consecutive values, where N is the number specified for the Trendline.Period.
|
Polynomial
|
Calculates a least square fit using a polynomial curve of order equal to the number specified by the Trendline.Order property. The equation is in the form y = b + (c1 * x) + (c2 * x^2) + … + (cN * x^N) where N is the trendline order.
|
Power
|
Calculates a least square fit for a power curve in the form y = a * x^b.
