Description
The FLIM package can be used to fit linear models for the observed increments of longitudinal processes found in longitudinal datasets. In addition, it can reconstruct any missing data by imputing estimated values according to the fitted models. The mean structure of the reconstructed data will be correct under certain assumptions. However, imputed data will not exhibit the random variation it should, and pointwise confidence bands can be based on bootstrap samples.

Package: FLIM
Type: Package
Version: 1.1
Date: 2013-12-09
License: GPL-2
The model fits and reconstruction is done with the core function flim, and mean responses can be calculated with flimMean. To investigate results graphically one can use plot.flim.
To assess model fits at each observation time after having used flim, see flimList.
A bootstrap function flimboot for "flim" objects is implemented as well.
