Standard DeviationHello. Can someone help me on this ? #2 20130225 21:20:24
Re: Standard DeviationHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20130225 22:35:12
Re: Standard DeviationStandard deviation like a mean works on a list of elements not on 3 at a time. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20130322 01:35:29
Re: Standard DeviationHello again #5 20130322 01:39:17
Re: Standard DeviationThere are several ideas but I would need to know a little bit more. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #6 20130322 02:10:16

Re: Standard DeviationOkay, what are you trying to do with that? Do you have some other array to compare it to? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #8 20130322 02:26:52
Re: Standard Deviationit would be easy to compare it with another array, slot by slot. But i want to get a value out of each array. Thinking of the array as a graph> can i get a value out of it? area perhaps?distance of the area from 0? perhaps 2 or 3 small areas on a graph separated by 0 color values? sorry i can not think anything to compare 2 graphs that may look completely different. #9 20130322 02:35:11
Re: Standard DeviationYou want to turn the array into a single number? This could very well take much more time than comparing them element by element. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #11 20130322 02:44:18
Re: Standard DeviationYou are using some programming language? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Standard DeviationDoes the new C++ have multiprecision arithmetic yet? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #14 20130322 02:54:03
Re: Standard DeviationI don't know what is this. Last edited by panicoschr (20130322 02:54:25) #15 20130322 02:56:06
Re: Standard DeviationIt still only has 16 digits of precision is what I mean. Basically that means only 16 digits in any number. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #16 20130322 03:14:59
Re: Standard DeviationNo, not exactly. Remember order counts in your array so you just can't add up the numbers or multiply them. The simplest thing of course is the decimal system. How high are the numbers in the each array? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Standard Deviationsorry i had to leave for some time. I made a small testing , saw max no = 160. Of course most of the slots are value 0. Lets say only 30 slots have a value {3,4, 10 , 20 , 34 etc) #18 20130322 09:40:17
Re: Standard DeviationHmmm, that is going to be a problem. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
