cross correlation/convolution?
966134
Convolution and correlation are both names for mathematical operations, just like multiplication, division, addition, etc.\n\nThe difference is that where convolution is described by flip=>slide=>multiply and integrate, correlation does NOT flip one of the inputs. So to correlate two signals, simply perform the slide=>multiply and integrate operations for the total overlap of the two signals.\n\nCross correlation is just the name that is used to denote the result of performing the correlation mathematical operation on two different input signals. Conceptually, a cross correlation tells how alike two signals are, even though they may not be aligned in time. When two signals are alike, a large peak appears in the cross correlation.\n\nAutocorrelation is a special case that describes the correlation of a signal with itself. The useful property of an autocorrelation is that an autocorrelation of a periodic signal is itself a periodic signal.\n\nThe above is a signals and systems or DSP centric answer, Wikipedia can better address the statistics answer.

No. there is no such software. However there are convoluted ways to do that.

It is explained here:\n\nhttp://en.wikipedia.org/wiki/Pearson_product-moment_correlation_coefficient

Think of it as attempting to approach an impulse in the frequency domain.  The fourier transform of an impulse is a constant.  Try this:\n\nb = fir1(100,0.000001);\nstem(b)\n\nAll of the filter coefficients are positive.  Your result will look almost like a Gaussian distribution. That's the result of convolution.  Your filter coefficients are trying to "knock down" anything that is periodic.

yes, using OCR - optical caracter recognition. But it will be very very slow and you will need a mouse.

There are lot of softwares for this kind of Job. You can try "ImTOOMpeg Encorder". It can convert lots of different file types.

My webcam came with software that will do it.  Some handicams will also do it, but it's less common than not.

You might try DAP. You can find it here along with a lot of other free statistical software.\nhttp://members.aol.com/johnp71/javasta2.html

A few that come to mind at Euler, Maxima and Octave. Unfortunately, I don't think any of the free packages come close to Mathematica or Matlab, but maybe one of them will still meet your needs.

I do not know a preprogrammed utility to do this, but can point you in the direction that you might need to go.  See the reference below for the math and an on-line converter:

The variables invovled can be correlated.  Below is a link for the multiviate normal.  Notice that the variance-covariance matrix Σ is not restricted to be diagonal; it can be a general matrix, it just has to be positive semi-definite.  Note that if |Σ| = 0, then the pdf does not exist.  Anyway, the link includes the pdf (in the positive definite case of course), bivariate case, and the conditional distribution, which is also normal.  I have been using this distribution a lot in my research.

Convolution is a method of signal processing used in phones, radio, cd's, and many more. It is used to filter out noise, and reinforce signal quality.\n\n<how does it pertain to every day life?> \nWell, it depends. The above is a list of things that affects people daily, however, average people never need to think of such things, typically only electrical engineering folk.

you should use matlab.

Yes, it shows correlation.\n1 = perfect positive correlation\n-1 = perfect negative correlation.

I find it hard to believe that the pairs are treated independently. There's no point to that, it doesn't give you any useful statistical information.\n\nHowever, if you're trying to compare all the values on the left side as a group with their pairs on the right side as a group, then you could use a modified version of the Chi^2 test. Basically multiply everything by 100, and then do a normal Chi^2 test.\n\nYour degrees of freedom will be (6-1)(2-1) = 5
