Here we calculate the price-earnings (pe) ratio for the companies three different ways. If you want that labelled, one approach is to produce string concatenations and then call up labmask to copy its values to value labels. Numeric variables result from any expresion made up of functions/methods and operators that return a numeric value for each row. group() alone is enough to produce a numeric identifier. In this case, pain is an ordinal variable. However, in figure 2, pain intensity is analyzed in different categoriesnone, mild, moderate, severe. In this case, pain is a numerical variable. do repeat conv s1 to s4 / ori c1 to c4 /. In figure 1, the numeric rating scale is used to record pain for each group at each time point in the study. For each variable, flag conversion failures: cases where converted value is system missing but original value is not empty. recode s1 to s4 (else copy) into c1 to c4. | 670007164928 670007164928 670007181020 |įor numeric identifiers, I still favour group() with labels and there should be automatic promotion to whatever storage type is needed.Įgen label = concat(var1 var2 var3), format(%13.0f) p(" ")ġ. The approximate numeric data types are FLOAT (p), REAL, and DOUBLE PRECISION. Exact SQL numeric data type means that the value is stored as a literal representation of the number's value. Integers Integers are whole numbers, such as 1, 20, 3000, 10200305, etc. There are no other variable types in SPSS than. You cant do calculations on string variables -even if they contain only numbers. String variables may contain letters, numbers and other characters. For a start, we will describe the most common types integer and floating-point values. SPSS has 2 variable types: Numeric variables contain only numbers and are suitable for numeric calculations such as addition and multiplication. Numbers are usually stored as integers, floating-point values, or complex numbers, depending on the requirements of the program.
