Member nameDescription
xlExponentialUses an equation to calculate the least squares fit through points (for example, y=ab^x) .
xlLinearUses the linear equation y = mx + b to calculate the least squares fit through points.
xlLogarithmicUses the equation y = c ln x + b to calculate the least squares fit through points.
xlMovingAvgUses a sequence of averages computed from parts of the data series. The number of points equals the total number of points in the series minus the number specified for the period.
xlPolynomialUses an equation to calculate the least squares fit through points (for example, y = ax^6 + bx^5 + cx^4 + dx^3 + ex^2 + fx + g).
xlPowerUses an equation to calculate the least squares fit through points (for example, y = ax^b).
