Empirical dynamic modelling
edm implements a series of tools that can be used for empirical dynamic modelling in Stata. The command keyword is edm, and should be immediately followed by the subcommand
xmap. A dataset must be declared as time-series or panel data by the
xtset command prior to using the edm command, and time-series operators including
s. can be used (the last for seasonal differencing).
edm command can be installed in Stata via the command
ssc install edm. The source code is available from RePEc.
alignmicro implements some of thecommon microsimulation alignment algorithms for binary variables as described in Li and O’Donoghue (2014) in Stata. The command creates a binary variable as an output, based on the original probability, overall target probability, and the alignment method selected.
alignmicro command can be installed in Stata via the command
ssc install alignmicro. The source code is available from RePEc.
rdecompose implements the Das Gupta’s rate decomposition method for aggregated data in Stata. The command reports the contribution of each specified variable to the aggregate value. The command keyword is
rdecompose. It should be immediately followed by the names of the variables (factors) that contribute to the rates. The population indicator also must be included in the option group. For more information is available from Li (2017)
rdecompose command can be installed in Stata via the command
ssc install rdecompose. The source code is available from RePEc.
STINMOD+ is a microsimulation model that calculates the effects of tax and transfer policy on disposable incomes. It comprehensively models the tax and transfer system in Australia and includes all personal taxations and federally administered welfare payments other than NDIS. The model replicates the implementation of the programs in real life, incorporating elements such as income testing and asset testing. STINMOD+ can also be linked with other economic and behavioural models.
STINMOD+ offers an online access version from its website. The availability of the remote access client which allows unit record access is subject to the approval of NATSEM.
