comment histogram of imported data shows a single bin
You have two outlying data points that are so far out the auto binning puts everything else in one bin. Use Select to filter the data: Histogram[Select[intervals,#<.2&]]

comment Old fashioned region method?
you question seems to only be about the limit specification? It seems you are correct that this is not mentioned in the Plot3D documentation, but it is pretty much standard convention among similar functions that take multidimensional ranges that reading left to right the limits of each variable can depend on those before it (Table, Integrate, etc ). No need to be concerned it should go away.

comment Export data from Array to *.csv without curly brackets
Have you also defined heatcombarrayex[2]? Otherwise I don't understand what you are doing with Array. In any case show what heatcombarrayoutex looks like in mathematica.

I'm guessing you are not correctly interpreting the python domain usage..

comment Is there a IsDefinedQ function?
isDefinedQ[f_, args_] := MemberQ[(First@Cases[#[[1]], f[x__] :> {x}]) & /@ DownValues[f] , args] (Obviously you would not use this for the present problem)

comment Is there a IsDefinedQ function?
Note the literal question is not a duplicate. ValueQ does not work because its argument is first evaluated. ( I suspect you need to parse the results of DownValues )

comment 1/x integration giving 0 instead of infinity
Reviewing the docs for GenerateConditions I don't see the part about turning off safety checks, or how only experts should use it and should be prepared to be happy with patently wrong results.

comment NonlinearModelFit::nrnum error
The error indicates your data probably contains some non-numeric junk. Try this: ArrayQ[data[[1, 11 ;;]], 2, Element[#, Reals] &] (the second arg is 1 or 2 depending on the dimension of the data )

comment ListLogPlot error when forcing y axes start at 0
indeed, v10 works better in the sense that it ignores the zero and respects your upper limit. use Quiet@ListPlot to suppress the message.
