YAC Data On-Line now includes a second functionality - a viewer of predefined reports (alongside already available wizards for defining new analyses). Reports may contain tables and charts, and can be recalculated for predefined target groups and/or waves. This allows for very quick distribution of results to clients.

YAC Data On-Line (YDOL) preview, a version of our data analysis program that runs under internet browsers, is already available for your evaluation - please use this link to go the application's pages.

YAC Data Kit in version 2.20 adds the possibility to define and analyze questions that are defined by several dimensions (or axes), such as:- opinions x evaluation (how strongly respondents agree or disagree with an opinion) with labeled and numeric scales,
- statements x brands (which brands fit a given statement),
- statements x brands x scale (how well each brand fits a given statement).
Based on tables with results from multi-dimensional questions, new types of charts may be easily prepared.

YAC Data Builder 2.10 - the program for importing data into YAC Data Analyzer - in the previous version was a console application. Currently it is an integrated GUI environment that contains a fully functional script editor for .dbs files and many functions that help and ease script preparation and data processing:- an import utility that loads data directly from SPSS (.sav) files and allows for defining the data's structure (modules, question definitions),
- syntax highlighting,
- column blocks,
- search / replace with regular expressions and incremental search,
- multi-level undo and redo,
- macro recording and playback,
- script validation,
- data processing directly from the editor,
- run YAC Data Analyzer automatically on the processed data,
- make-type utility that processes only the changed parts of the documentation and data,
- and many, many more...
The previous console version is still available (for batch processing).
Press analysis extensions in YAC Data Analyzer 2.10 include:- handling of readership data by days for dailies in general analysis and media plans,
- handling of data on the number of issues, circulation and sales (also by days of the week and by regions),
- calculation of indicators based on the number of issues, circulation and sales (e.g. cost of insertions / sales),
- automatic importing and displaying of data collected by Zwiazek Kontroli Dystrybucji Prasy (Union for Control of Press Circulation).
Moreover, many smaller extensions were added that should help in day-to-day program usage.

YAC Data Analyzer 2.00 introduces press media plan optimization. Genetic and randomization algorithms are used to find media plans that meet one or more criteria, but can also optimize for two or more values (such as OTS 1+ and Freq) at the same time. Optimization for two or more target groups is also supported.
Full export of reports (including charts) was also added to the program.

The next version of YAC Data Analyzer (1.20) introduces press readership data analysis, with calculation of advertising campaign indicators (media plan). You can compute all kinds of readership indicators, such as last issue readership, average issue readership, season cycle readership, number of issues read, number of contacts with an issue, readers per copy, and many more. Moreover, the following functions are available:- preselection of titles based on the regions they are issued in,
- seamless transition from the readership analysis module to the media planning module, or rather the possibility of joint analysis of readership and media planning indicators,
- OTS and OTS+ computations on any level (e.g. OTS 10, OTS 20+),
- merging of OTS levels (e.g. OTS 1:3),
- analysis of all indicators by waves of the survey and in various target groups,
- crossing of all indicators with other questions,
- analysis of coreadership and structure,
- simultaneous analysis of many price lists,
- analysis of only those readership and media plan indicators which are of interest to the user,
- all data may be analyzed for groups of titles,
- the CPP and CPM indicators are available in GRP, Reach, and Effective reach flavors (for any level of effective reach, e.g. OTS 3+),
- population estimation of the indicators: AIR, GRP (i.e. Gross Impressions), OTS, OTS+.
In price lists you can define advertisement prices for all titles and various types of ads, and you can set a default price - one that will be automatically taken for new analyses. Price list comparison allow to take into account all kinds of promotions, discounts, packages, and other kinds of special offers.

In the new version of YAC Data Analyzer (1.10) you can analyze radio audience data. The following indicators may be computed: spontaneous and prompted awareness, weekly and daily reach, and reach in quarters. The analysis may be crossed by the places of listening and radio signal source. You can also analyze the mean time of listening, market share, and average quarter audience. The program allows for trends analysis, comparison of target groups, calculation of audience structure, colistening of stations and crossing of all indicators by any of the other questions.
All this in flexible pivot tables with the possibility of estimation of the results to the surveyed population, sorting, aggregated analysis for groups of stations, days of the week, time segments and other parameters. You also get: preselection of stations based on emission regions and easy report exports to other applications.

After nearly four months of intensive work we are ready to present the first version of our analytical software: YAC Data Analyzer. Most of our efforts were directed at creating a general platform for the development of various kinds of analyses in the future, but with this version you already get multi-dimensional pivot tables with nested parameters, a fully operational charting module, multi-wave analysis, complex filter (target group) definitions, standard descriptive statistics, analysis of weighted data, and automatic data recalculation after installation of new data. The application is bilingual (Polish-English with the possibility of extension to other languages), the survey texts may be in one, two or more languages.
