The Dismod_at Data Flow#

Discussion#

Tables are used to transfer information from one command to another. Each of the output tables below is created by a command . Some of the extra input tables may be created, or replaced, by the dismod_at user. Also note that a row is written in the log table at the beginning and end of every command. In addition, the log table is cumulative; i.e., it is never erased and restarted.

Output Tables by Table Name#

Below is a list of the dismod_at output tables by table name: The ones that can be created directly by the user have yes under By User.

Table	Output By	By User
bnd_mulcov	bnd_mulcov	no
age_avg	all except python and set commands	no
data_sim	simulate	no
data_subset	init , hold_out	no
depend_var	depend	no
fit_data_subset	fit	no
fit_var	fit	no
hes_fixed	sample	no
hes_random	fit , sample	no
ipopt_info	fit	no
log	all commands	no
mixed_info	fit	no
predict	predict	no
prior_sim	simulate	no
sample	sample	yes
scale_var	init , set	yes
start_var	init , set	yes
trace_fixed	fit	no
truth_var	set	yes
var	init	no

Command Output Tables#

Below is a list commands and their corresponding output tables:

Command	Output Tables
depend	depend_var , age_avg
bnd_mulcov	bnd_mulcov , age_avg
fit	fit_var , fit_data_subset , age_avg , trace_fixed , hes_random , mixed_info , ipopt_info
hold_out	data_subset
init	age_avg , var , data_subset , start_var , scale_var , bnd_mulcov
predict	predict , age_avg
sample	sample , hes_fixed , hes_random , age_avg
set	start_var , scale_var , truth_var
simulate	data_sim , age_avg

Command Extra Input Tables#

An extra input table is one that is not in the input table list and is not output by the init_command (see list above). Below is a list commands (that have extra input tables) and their corresponding extra input tables:

Command	Extra Input Tables
fit	data_sim
predict	sample fit_var truth_var
simulate	truth_var
sample	fit_var data_sim prior_sim
set	fit_var sample
