Posting this under the heading it deserves: Aggregated purity results across four services, with caveats Everything below is what sits behind that.
Aggregated purity results across four, from the point of view of someone who has read the documentation and is still stuck.
Saying which parts I have understood so that nobody wastes time re-explaining them, and where exactly the understanding stops.
A codebook describing each field takes twenty minutes and is what makes the file usable by anyone but you. Most shared datasets here do not have one.
The part I am sure of is shorter than the part I have written.
Post #2 describes the usual case. This is about the unusual one.
Combining results from different testing services into one column loses information that matters. Keep the service as a field.
If this contradicts something upthread, the upthread version may well be the better one.
