comment Problem with writting into a matrix in Mathematica
Incidentally, MatrixPlot[S, ColorFunction -> ColorData["RedGreenSplit"]] can be quite pretty using my specification.

comment Implementation of Partial Least Squares (PLS)?
This would be a really nice application of NestList, if only I had time today.

comment Manipulating a damped oscillator plot - plot does not show
It's the same essential problem, @xzczd, but I decided not to close it because there was another issue that I wanted to alert the OP to - see my answer. Happy to be overruled by the community if it comes to it.

comment solve two coupled nonlinear partial differential equations for 2 functions with space and time variables
Welcome to SE! I formatted your code for you. May I suggest that you take the Tour and have a look at the other information available to help people use the site effectively?

comment Traffic growth forecast: showing the change of linear regression
I don't think there is a "best" tool for a relatively straightforward econometric analysis like this. You could do it in R, in Mathematica-plus-R, or eViews, or any number of econometric tools.

comment Add assumptions to Solve command
Welcome to Mathematica.SE @MathHelpNeeded! I suggest: 1) You take the introductory Tour now! 2) When you see good questions and answers, vote them up by clicking the gray triangles, because the credibility of the system is based on the reputation gained by users sharing their knowledge. Also, please remember to accept the answer, if any, that solves your problem, by clicking the checkmark sign! 3) As you receive help, try to give it too, by answering questions in your area of expertise.

comment Control legend size when autoLegend is used with LinTicks
Glad I could help. If you are a beginner I would suggest trying to do simple things first, like using the built-in legending functionality instead of taking custom stuff from this site that was designed for an earlier version of the program. Since you mention in another comment that you are using version 9, none of this extra complexity is necessary.

comment How to use PlotMarkers or Mesh with Plot to creat Marks on the plot
@MichaelE2 Yes, but isn't it odd that the default colors don't resolve to an existing scheme?

comment Reduce gives wrong solutions
Hello, and welcome to Mathematica.SE! This is an interesting point and link, but as it stands, your answer is more a comment than a full answer. Could you please expand on it a little, say, by summarising the content in the linked post?

comment DensityPlot colours symmetric around zero
I have to admit I didn't test the function extensively. Glad I could help! By the way, according to the documentation, NMaxValue etc also only find local minima, unless f is linear.

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 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.
