Overview (RESPONSE RATE command)

RESPONSE RATE calculates group response rates and cumulative group response rates, expressed as a percentage, where response rate is calculated as NUMERATOR divided by DENOMINATOR for each category of GROUP, and cumulative response rate is calculated as the cumulative sum of NUMERATOR divided by the cumulative sum of DENOMINATOR for the current and all preceding categories of GROUP.

• Output includes a table of response rates, sum of the DENOMINATOR variable, cumulative response rates, and cumulative sum of the DENOMINATOR variable in ascending order of the GROUP variable, and a line chart of response rates and cumulative sum of the DENOMINATOR variable.
• If MINRATE or MAXCOUNT are specified, the table is color-coded based on the specified cumulative value(s), and the line charts include reference lines at the specified value(s).

The RESPONSE RATE command is intended primarily for use as part of the Postal Code Response Rate dialog interface, and some of the results refer to a new, aggregated dataset that is created by the dialog interface. See the topic Postal Code Response Rates for more information. When you use the RESPONSE RATE command outside of the Postal Code Response Rate dialog interface, this new, aggregated dataset is not created. See the topic Postal Code Response Rates for more information.

Basic specification

• The basic specification is the command name RESPONSE RATE and a VARIABLES subcommand.
• The MINRATE and MAXCOUNT subcommands are optional.

Operations

• Cases with missing values for any variables specified on the VARIABLES subcommand are excluded from the analysis (listwise deletion).
• If the sum of DENOMINATOR is 0 or negative for a value of GROUP, that group is excluded from the analysis.

Subcommand order

Subcommands can be specified in any order.

Syntax rules

• The VARIABLES subcommand is required.
• The VARIABLES subcommmand must include NUMERATOR, DENOMINATOR and GROUP variables.
• Equals signs (=) shown in the syntax chart and in examples are required.
• Command, subcommand, and keyword names must be spelled out fully. Abbreviation is not allowed.
