### Modeling data

```I have a modeled data set R_mod which is a dependent on 5 other variables. Individual relationship of R_mod with 5 independent variables are polynomial relationships. Now i want to fit measured data R_mea with modeled data R_mod by adjusting 5 independent variables. Please suggest me how can perform this...i have another question as there will be infinite number of solutions to this problem how can i pick the reasonable solution.....thanks in advance...

```Many things to think about... I suppose you could try linear regression, extract the coefficients, and compare them to what your model produces.

You should check that the predictors aren't correlated, otherwise your coefficients will be junk (/www.graphpad.com/articles/Multicollinearity.htm)

Data mining and data extraction
I have a question on how to write a script in matlab to help me look throw a bunch of data and extract data that was selected based on my criteria. I have a text file with about 1.5 million rows and 5 columns they are separated by a space. I am able to load that file “x=dlmred(‘myfile.txt’,’’) and matlab reads it. I need to index the data into 2 sets 1st column with is used to sort the data and find start and end to each data set and the second index witch has the data that is relates to each row. I need matlab to take chunks of data for example : (searching|(data that is related to each search index) index) | 1 118 254 5 4 1 98 1 8 6 1 84 23 8124 1 1 894 21 1 44 1 84 21 1 5 2 894 8748 874 8 2 87489 8 54 484 2 848 3 4 3 3 513 8 848 2 3 7456 1 4 21 3 897 23 48 15 3 94 88 8 4 5 9 2 84 418 5 99 9 4 8 5 32 2 48 4 5 8 79 8 84 And I need to extract data from 1 to 1as my searching index however I to pull all the related data to from the search to be extracted into a new text file for other analysis. Please let me know what I should do and how should I approach this problem. On 10/17/2013 9:33 AM, Dimitry wrote: .... > I need to index the data

Data Structures...
VB6 doesn't provide many commonly used data structures such as Hashtables, so I was wondering are there any implementations\libraries out there that provide some extra data structures above Collection? Any help greatly appreciated..

I don't think we're officially "supposed" to care about the implementation of the collection. :-) Seriously, there are many sites that have data structures. "Slice and Dice" from William M. Rawls has some data structures, but no hash implementation, that I know of. The hash implementation I have uses arrays - I got it from a copyrighted book so I don't think I should post it. James Vincent Carnicelli has some thoughts on ad-hoc data structures without the need for classes. VBDox, by Mihayl Stamenov has some data structures, particularly a dictionary - but it uses

Virtual Data?
Why doesn't c++ support virtual data? It supports class data of type pointer to function (that's what virtual functions really are). In terms of implementation, why can't I have other types of data in my vtable? RTTI could be implemented this way instead of as a special case for the compiler. It would also be useful for class specific memory management implementations. -- Daniel A.

Validating Data

Export data..
Hi All, i use "mysqldump" with "--skip-opt --dump-date" options to export single table, but the output contain create table statment and the insert and i have error in inport phase (table already exist):(.

data members
data members defined after a private label are not accessible to code that uses the class. So, can I define the private data members as const? asdf wrote: > data members defined after a private label are not accessible to code > that uses the class. > So, can I define the private data members as const? > Have you tried it? Why do you think you could not? -- Ian Collins. * asdf: > data members defined after a private label are not accessible to code > that uses the class. You seem to have the right idea, roughly, but consider: * What if after a "private:" I put a "public:" and some data member declarations? Then they are certainly /after/ the "private:". * What if the code that uses the class is in member functions of the class itself? > So, can I define the private data members as const? Yes. But generally you should only use const members for a class that's designed to be non-copyable (less imprecisely: for a class whose instances are non-copyable by design). Using a const or reference member prevents ordinary assignment (the member can not be changed) but not copy construction (the member
