comment the “natrual value”and the “Pruning”
Welcome to Mathematica.SE! May I suggest that you split this into two separate questions? They are very different.

comment Plot axes are not exported to SVG properly in Mathematica 10.1
I can't reproduce in V10.1 for Windows 7. A browser issue?

comment Delete data were y = “NS” in a list with elements {x, y}
Thanks for your attempt at an answer! Could you perhaps add a bit more explaining your approach and (ideally) how it compares to others? What if the non-numeric element isn't exactly "NS"?

comment SetSystemOptions in a package
Thanks @halirutan - yes, that's the correct edit. Was in a hurry and had forgotten how to do it right. Anyway, the wrinkle I hadn't mentioned is that the packages are in Eclipse Juno, and I'm launching version 10 from there. I don't have write access to the production version of the packages because our IT dept locks access to that folder. (I'm on Windows 7 here.)

comment how can I change the length/size ticks in a framed plot?
@LLIAMnYP You can, of course, include them as well, but I chose a simple example that the OP could work with. I've added that case.

comment how can I change the length/size ticks in a framed plot?
I'm surprised that I couldn't find a dupe for this, but it seems it hasn't actually been asked before.

comment How to access data from WHO Mortality Database
Check out the Import function, which supports ZIP files. You would need to know the internal structure of the ZIP archive to see if there are any directories within it.

Have a look at ListInterpolation

comment Help with functions in Mathematica
@m_goldberg - I'm guessing ToCharacterCode? Connor, you might not need your own function for this.

comment Copy/export a plot as vector EMF
The Opacity trick definitely works. Your issue is not the EMF issue, it's that you can't use Export at all.

comment Time inhomogeneous Markov Chain in Mathematica
I haven't time to work this out myself but something involving FoldList and an Array of the relevant transition matrices should work. The main catch is that RandomFunction outputs TemporalData, so you might need to use ["Paths"] to strip it back to a plain list.

comment Iterating a model with 2nd order difference equations using Manipulate
jones, please don't post another version of the same question just because the prior one was closed. Edit the old question to improve it (thus fixing the reason for its closure) and click "flag" to have it reopened. As a gesture of goodwill I've reopened the previous one.

comment Kalman filter estimation
@Nasser - could you perhaps work this up into an answer with a couple of examples? And Luke, welcome to Mathematica.SE! I hope you find the site useful.

Dear Dennis, welcome to Mathematica.SE! It would help if you posted code showing what you have tried.

comment Periodogram for irregularly spaced data
@Sektor - I've pasted the data in for the UK at least.

comment Periodogram for irregularly spaced data
@MikeHoneychurch - unfortunately Periodogram doesn't take TemporalData in v9, and I don't think that's changed in v10.

comment Periodogram for irregularly spaced data
One can apply a LowpassFilter to the data before drawing the Periodogram, but given that their whole thesis is about the relative importance of other bits of the spectrum, that's a bit odd.

comment How to simultaneously change variables shared by several functions?
It's not clear to me what you mean. Do you mean you want to be able to define your functions to take variable numbers of arguments (in which case define them like this: condition1[args__]:=...), or do you just want to use the same list of inputs for several functions (in which case have a look at Through)?

comment How to control pedestrians to enter the simulation region with random functions?
I would suggest getting the constant-probability-of-entry case working first. Also, you might have better results if you don't use subscripts. Have a look at some of the suggestions in this question.

If you are the original poster, but just didn't fully register the first time this link might be helpful. If you merge your accounts, the rep you gained from the question will be added to that earned from the answers.
