PSPP SYNTAX MANUAL

Numeric variables that have no value at all are called «system missing». This allows you to exclude this answer from analyses. Suppose you have coded as value -1 the answer “ I prefer not to answer” to the question that generated your age variable. On both numeric and string variables you may mark one or more values as MISSING. While numeric variables are all of one and the same type even in the presence of different display formats, string variables of different lengths are considered to be different: PSPP will refuse to combine two files that have string variables of the same name but of different lengths. Adjacent variables may be specified using first TO last ( sex TO profession). You specify sets of variables leaving whitespace (and not commas) between their names: sex age education profession.

String values may be concatenated with the ‘+’ operator: COMPUTE footNote = 'Missing values are ' +ĬOMPUTE footNote = 'Missing values are excluded from this ' +ĬOMPUTE footNote = 'Missing values are excluded from this table.'. Double the quote when you need to «escape» one: ( 'Maxim''s'). String values have to be enclosed in pairs of single ( 'Septime') or double ( 'Maxim's') quotes. String variables have to be declared explicitly with the STRING command, specifying their (maximum) lengths. Variables in PSPP are either numeric (the default) or string. Let me try to sum up the basics of syntax.

Better yet, the command you pasted look it up in the PSPP manual and trim it down to what is essential. My advice: in PSPPIRE always choose Paste instead of Run and keep the syntax file you generate this way. What is great about PSPPIRE is that it is not just an alternative to issuing commands in PSPP’s language (the “syntax”): it actually is a syntax generator! Learning on the job … Besides, when I need to process really big data, I don’t want to waste time and memory on a spreadsheet-like visualization. Not all these steps are as easy as a mouse click. An analysis is usually the finishing touch in a process that involves many steps: reading, reshaping, checking, coding, re-coding, re-checking. Does that mean that I can do my analyses without having to learn yet another language?
