Abstract
As Forest Inventory and Analysis (FIA) changes from periodic surveys to the multipanel annual survey, new analytical methods become available. The current official statistic is the moving average. One alternative is an updated moving average. Several methods of updating plot per acre volume have been discussed previously. However, these methods may not be appropriate for updating more detailed data such as diameter distribution and species composition tables. Several methods for updating these more detailed data will be compared. Methods to be compared include imputing whole tree lists from donor plots and imputing all the individual trees for each plot. The data from the last periodic survey of Georgia and Georgia's first panel will be used to compare the different imputation methods.
