#'
#' ADJUSTMENT FACTOR:\cr The adjustment factor is necessary to account for
#' nonsampled conditions. It is calculated for each estimation unit by strata.
#' by summing the unadjusted proportions of the subplot, microplot, and
#' macroplot (i.e. *PROP_UNADJ) and dividing by the number of plots in the
#' strata/estimation unit).
#'
#' An adjustment factor is determined for each tree based on the size of the
#' plot it was measured on. This is identified using TPA_UNADJ as follows:
#'
#' \tabular{llr}{ \tab \bold{PLOT SIZE} \tab \bold{TPA_UNADJ} \cr \tab SUBPLOT
#' \tab 6.018046 \cr \tab MICROPLOT \tab 74.965282 \cr \tab MACROPLOT \tab
#' 0.999188 \cr }
#'
#' If ACI=FALSE, only nonsampled forest conditions are accounted for in the
#' adjustment factor. \cr If ACI=TRUE, the nonsampled nonforest conditions are
#' removed as well and accounted for in adjustment factor. This is if you are
#' interested in estimates for all lands or nonforest lands in the
#' All-Condition-Inventory.
#'
#' sumunits:\cr An estimation unit is a population, or area of interest, with
#' known area and number of plots. Individual counties or combined
#' Super-counties are common estimation units for FIA. An estimation unit may
#' also be a subpopulation of a larger population (e.g., Counties within a
#' State). Subpopulations are mutually exclusive and independent within a
#' population, therefore estimated totals and variances are additive. For
#' example, State-level estimates are generated by summing estimates from all
#' subpopulations within the State (Bechtold and Patterson. 2005. Chapter 2).
#' Each plot must be assigned to only one estimation unit.
#'
#' stratcombine:\cr If MAmethod='PS', and stratcombine=TRUE, and less than 2
#' plots in any one estimation unit, all estimation units with 10 or less plots
#' are combined. The current method for combining is to group the estimation
#' unit with less than 10 plots with the estimation unit following in
#' consecutive order (numeric or alphabetical), restrained by survey unit
#' (UNITCD) if included in dataset, and continuing until the number of plots
#' equals 10. If there are no estimation units following in order, it is
#' combined with the estimation unit previous in order.
#'
#' autoxreduce:\cr If MAmethod='GREG', and autoxreduce=TRUE, and there is an
#' error because of multicolinearity, a variable reduction method is applied to
#' remove correlated variables. The method used is based on the
#' variance-inflation factor (vif) from a linear model. The vif estimates how
#' much the variance of each x variable is inflated due to mulitcolinearity in
#' the model.
#'
#' rowlut/collut:\cr There are several objectives for including rowlut/collut
#' look-up tables: 1) to include descriptive names that match row/column codes
#' in the input table; 2) to use number codes that match row/column names in
#' the input table for ordering rows; 3) to add rows and/or columns with 0
#' values for consistency. No duplicate names are allowed.
#'
#' Include 2 columns in the table:\cr 1-the merging variable with same name as
#' the variable in the input merge table;\cr 2-the ordering or descriptive
#' variable.\cr If the ordering variable is the rowvar/colvar in the input
#' table and the descriptive variable is in rowlut/collut, set
#' row.orderby/col.orderby equal to rowvar/colvar. If the descriptive variable
#' is the rowvar/colvar in the input table, and the ordering code variable is
#' in rowlut/collut, set row.orderby/col.orderby equal to the variable name of
#' the code variable in rowlut/collut.
#'
#' UNITS:\cr The following variables are converted from pounds (from FIA
#' database) to short tons by multiplying the variable by 0.0005. DRYBIO_AG,
#' DRYBIO_BG, DRYBIO_WDLD_SPP, DRYBIO_SAPLING, DRYBIO_STUMP, DRYBIO_TOP,
#' DRYBIO_BOLE, DRYBIOT, DRYBIOM, DRYBIOTB, JBIOTOT, CARBON_BG, CARBON_AG
#'
#' MORTALITY:\cr For Interior-West FIA, mortality estimates are mainly based on
#' whether a tree has died within the last 5 years of when the plot was
#' measured. If a plot was remeasured, mortality includes trees that were alive
#' the previous visit but were dead in the next visit. If a tree was standing
#' the previous visit, but was not standing in the next visit, no diameter was
#' collected (DIA = NA) but the tree is defined as mortality.
