Syntax basics and common commands

A command consists of the command word, the variables and subcommands with "/". It ends with a period. Command words are case-insensitive and may be abbreviated.

DESCRIPTIVES /VARIABLES=alter punkte
  /STATISTICS=MEAN STDDEV MIN MAX.

The commands behind the question types

• Groups, two: T-TEST GROUPS=group(1 2) /VARIABLES=points.
• Groups, more: ONEWAY points BY group /STATISTICS=DESCRIPTIVES HOMOGENEITY.
• Relationship: CORRELATIONS /VARIABLES=a b /PRINT=TWOTAIL.
• Prediction: REGRESSION /VARIABLES=… /DEPENDENT=… /METHOD=ENTER /STATISTICS=COEFF R ANOVA CI(95).
• Frequencies: FREQUENCIES /VARIABLES=… ; crosstab: CROSSTABS /TABLES=a BY b /STATISTICS=CHISQ.
• Scale: RELIABILITY /VARIABLES=… /MODEL=ALPHA; factors: FACTOR (see there).

Statable uses GNU PSPP 2.1.3. PSPP does not know some SPSS options; the command then reports an error. On every page "Show command" displays the exact syntax of the calculation.
