Hi Suzy, Just to be clear, are you sure you want to create numeric values? The usual reason for destringing a variable is that it IS a numeric variable that has typos which cause it to be regarded as text. Is this is a continuous variable that does have a numeric (linear etc) relationship. If each of these string variables represent different disorders, you should have a good methodological reason for making them numeric. Otherwise, keep them in an "apples and oranges" arrangement of strings, i.e. diabetes (1003) is not "one more than" malaria (1002)... In essence, if you want to use each of these variables as categoricals, they are fine as is - as strings. You will be able to analyze them as strings, in a categorical or dummy variable sense. I may be way off here, but just wanted to make sure you knew you could analyze them as is..... Apologies if I am being obvious.

How can I successfully "destring" these values so that I can include | them in my analysis? | | Any help and/or specific code would be very helpful as I am only | marginally competent with Stata basics. | | Thank you! | Suzy | | | * | * For searches and help try: | * http://www.stata.com/support/faqs/res/findit.html | * http://www.stata.com/support/statalist/faq | * http://www.ats.ucla.edu/stat/stata/ | * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
