calcFX: Calculates the appropriate F(X) value of each observation
In ACCLMA: ACC & LMA Graph Plotting

Description Usage Arguments Value Author(s) Examples

Calculate the F(X) of each obseravtion by summing the F(X) of the previous observation with the weight of the current observation, should be used only after the calcWeights has been used on the source matrix

1	calcFX(mat)

mat

A data set that has the X,Y,Weight columns after calcWeights and reduceSameXs has been used on it

Return a data set with the F(X) column calculated
