Boolean variables related to check boxes (checked = true), were coded as 1 for checked = true, and `null` (blank) for unchecked = false.[[BR]]b. Boolean variables not related to check boxes, were coded as 1 for true, and 0 for false.[[BR]]c. Dates should be given in format YYYYMMDD, according to the variable description, but were given in format YYYY-MM-DD in the export file.[[BR]]d. Float values were given with 2 decimals using a decimal comma, according to the variable description, but were given with 2 decimals using a decimal point in the export file. (Sweden, like most countries in central Europe, historically used a decimal comma, but after computers were used more regularly, technical and natural sciences converted in the 1970's to using a decimal point.) |
