Primary suppression with the safety_rules options :

In tab_rtauargus() function, the primary suppression options have to be set in the safety_rules argument. By default this parameter is set to “MAN(10)”, useful when using apriori and Interval protection level of 10%.

If you want to set rules for primary suppression the syntax is : - “rule_number1|rule_number2|rule_number3|…” At least one safety rule is required.

These are all allowed rules according to τ-Argus manual.

The most common rules are :

  • The dominance rule NK(n,k) with :
    • n the size of the coalition
    • k the max percentage
  • The treshold rule Freq(n,p) with :
    • n the minimum frequency allowed
    • p the Frequency Safety Range
  • The p percent rule P(p,n) with :
    • the maximum accuracy of the estimation in percent
    • n (optional, default = 1), the size of the coalition
  • The safety margin MAN(p) with :
    • p the margin to use in percent

The other ones :

  • The request rule REQ(p1,p2,SafetyMargin)
  • The zero safety range parameter ZERO(p)
  • The status of missing codes MIS(b) with :
    • b = 0 (default) cells with a missing code is unsafe if the safety rules ares are violated
    • b = 1 these cells are always safe

Some rules can appear multiple times (P,NK)

You can get more details with the τ-Argus manual in the sections : - 4.4.4 Specify Tables - 5.7 The Batch command file

The suppress options :

The default options is “MOD(1,5,1,0,0)” It fits for our business statistics.

For each of the following parameters, the number of the table is needed, in our case it will always be 1.

The possible options are :

  • MOD: Modular :
    • MOD(TabNo, MaxTimePerSubtable, SingleSingle,SingleMultiple, MinFreq)
    • The last 3 parameters are the singleton options. Each parameter can be 0 or 1. If 1 the option is activated.
  • OPT: Optimal :
    • OPT(TabNo, MaxComputingTime)
  • GH Hypercube :
    • GH(TabNo, A priori Bounds Percentage, ModelSize,ApplySingleton)
    • ModelSize 0 = normal, 1 indicates the large model.
    • ApplySingleton: 1 = yes,0 = no; default = yes if the table has frequency-information, no if not.
  • NET: Network :
    • NET(TabNo)
  • RND: Controlled rounding :
    • RND(TabNo, RoundingBase, Steps, MaxTime, Partitions, StopRule)
    • Steps: number of steps allowed, normally 0 (default)
    • MaxTime: Max computing time (10 = default)
    • Partitions: 0, 1 (0 = no partitioning (default), 1 = apply the partitioning procedure)
    • StopRule: 1 = Rapid only, 2 = First feasible solution, 3 = optimal solution (3 =default)
  • CTA: Controlled Tabular Adjustment :
    • CTA(TabNo)
