Data Preparation & Descriptive Statistics
Data Preparation & Descriptive Statistics (ver. 2.4) Oscar Torres-Reyna Data Consultant [email protected] PU/DSS/OTR http://dss.princeton.edu/training/ Basic definitions… For statistical analysis we think of data as a collection of different pieces of information or facts. These pieces of information are called variables. A variable is an identifiable piece of data containing one or more values. Those values can take the form of a number or text (which could be converted into number) In the table below variables var1 thru var5 are a collection of seven values, ‘id’ is the identifier for each observation. This dataset has information for seven cases (in this case people, but could also be states, countries, etc) grouped into five variables. id var1 var2 var3 var4 var5 1 7.3 32.27 0.1 Yes Male 2 8.28 40.68 0.56 No Female 3 3.35 5.62 0.55 Yes Female 4 4.08 62.8 0.83 Yes Male 5 9.09 22.76 0.26 No Female 6 8.15 90.85 0.23 Yes Female 7 7.59 54.94 0.42 Yes Male PU/DSS/OTR Data structure… For data analysis your data should have variables as columns and observations as rows. The first row should have the column headings. Make sure your dataset has at least one identifier (for example, individual id, family id, etc.) id var1 var2 var3 var4 var5 First row should have the variable names 1 7.3 32.27 0.1 Yes Male 2 8.28 40.68 0.56 No Female Cross-sectional data 3 3.35 5.62 0.55 Yes Female 4 4.08 62.8 0.83 Yes Male 5 9.09 22.76 0.26 No Female 6 8.15 90.85 0.23 Yes Female 7 7.59 54.94 0.42 Yes Male id year var1 var2 var3 1 2000 7 74.03 0.55 Group 1 1 2001 2 4.6 0.44 At least one identifier 1 2002 2 25.56 0.77 2 2000 7 59.52 0.05 Cross-sectional time series data Group 2 2 2001 2 16.95 0.94 or panel data 2 2002 9 1.2 0.08 3 2000 9 85.85 0.5 Group 3 3 2001 3 98.85 0.32 3 2002 3 69.2 0.76 PU/DSS/OTR NOTE: See: http://www.statistics.com/resources/glossary/c/crossdat.php Data format (ASCII)… ASCII (American Standard Code for Information Interchange). -

R&D Centre for Mobile Applications (RDC) FEE, Dept of Telecommunications Engineering Czech Technical University in Prague RDC Technical Report TR-13-4 Internship report Evaluation of Compressibility of the Output of the Information-Concealing Algorithm Julien Mamelli, [email protected] 2nd year student at the Ecole´ des Mines d'Al`es (N^ımes,France) Internship supervisor: Luk´aˇsKencl, [email protected] August 2013 Abstract Compression is a key element to exchange files over the Internet. By generating re- dundancies, the concealing algorithm proposed by Kencl and Loebl [?], appears at first glance to be particularly designed to be combined with a compression scheme [?]. Is the output of the concealing algorithm actually compressible? We have tried 16 compression techniques on 1 120 files, and the result is that we have not found a solution which could advantageously use repetitions of the concealing method. Acknowledgments I would like to express my gratitude to my supervisor, Dr Luk´aˇsKencl, for his guidance and expertise throughout the course of this work. I would like to thank Prof. Robert Beˇst´akand Mr Pierre Runtz, for giving me the opportunity to carry out my internship at the Czech Technical University in Prague. I would also like to thank all the members of the Research and Development Center for Mobile Applications as well as my colleagues for the assistance they have given me during this period. 1 Contents 1 Introduction 3 2 Related Work 4 2.1 Information concealing method . 4 2.2 Archive formats . 5 2.3 Compression algorithms . 5 2.3.1 Lempel-Ziv algorithm . -

When it comes to digital steganography no stone should be left unturned in the search for viable hidden data. Although digital steganography is commonly used to hide data inside multimedia files, a similar approach can be used to hide data in archives as well. Steganography imposes the following data hiding rule: Data must be hidden in such a fashion that the user has no clue about the hidden message or file's existence. This can be achieved by -

How to 'Zip and Unzip' Files
How to 'zip and unzip' files The Windows 10 operating system provides a very easy way to zip-up any file (or folder) you want by using a utility program called 7-zip (Seven Zip). The program is integrated in the context menu which you get when you right-click on anything selected. Here are the basic steps you need to take in order to: Zip a file and create an archive 1. Open a folder in your machine and select any file (by clicking on it once). I selected a single file called 'how-to send an email.docx' 2. Now right click the mouse to have the context menu appear 3. In the context menu you should be able to see some commands like the capture below 4. Since we want to zip up the file you need to select one of the bottom two options a. 'Add to archive' will actually open up a dialog of the 7-zip application and will give you the opportunity to customise the archive. b. 'Add to how-to send an email.zip' is actually the quickest way possible to create an archive. The software uses the name of the file and selects a default compression scheme (.zip) so that you can, with two clicks, create a zip archive containing the original file. 5. Now you can use the 'how-to send an email.zip' file and send it as a 'smaller' email attachment. Now consider that you have just received (via email) the 'how-to send an email.zip' file and you need to get (the correct phrase is extract) the file it contains. -
