RATIO Subcommand (CSDESCRIPTIVES command)

RATIO specifies ratios of variables to be estimated.

  • Ratios are defined by crossing variables on the NUMERATOR keyword with variables on the DENOMINATOR keyword, with DENOMINATOR variables looping fastest, irrespective of the order of the keywords. For example, /RATIO NUMERATOR = N1 N2 DENOMINATOR = D1 D2 yields the following ordered list of ratios: N1/D1, N1/D2, N2/D1, N2/D2.
  • Multiple RATIO subcommands are allowed. Each subcommand is treated independently.
  • Variables that are specified on the RATIO subcommand do not need to be specified on the SUMMARY subcommand.
  • All specified variables must be numeric.
  • Within each variable list, all specified variables must be unique.
  • Plan file and subpopulation variables may not be specified on the RATIO subcommand.

The TTEST keyword requests t tests of the population ratios and gives the null hypothesis values. If subpopulations are defined on the SUBPOP subcommand, then null hypothesis values are used in the tests for each subpopulation as well as for the entire population.

value. The null hypothesis is that the population ratio equals the specified value for all t tests.

valuelist. This list gives the null hypothesis value of the population ratio for each ratio specified on the RATIO subcommand. The number and order of values must correspond to the ratios defined on the RATIO subcommand.

  • Commas or spaces must be used to separate the values.
