This page contains various simple statistics related to CAC-2006 (10th CAC), carried out by using available conference data and internet/literature data. The more universial character of chemotrics applied in various scientific areas and the growth of chemometric communities worldwide is an encouraging reason to perform general overviews, analyses and statistics about chemometric events, such as is CAC. The authors of this page hope that eventual readers will found out here some interesting and useful information.

The table below contains basic data of CAC (International Conferences on Chemometrics in Analytical Chemistry) conferences that were organized or are being organized in the presend moment. The first column provides links to conference sites (2002 and after) or sites with some online information related to the conferences (before 2002). Note that CAC conferences became regularly organized every two years after CAC-VII (2000) due to the growth of chemometric groups, societies and activities. The first conferences took place every four years.

CAC-2006 internet annoucement pages were collected at the end of 2006 and the beginning of 2007. The full report and brief statistics can be found in the corresponding page. Therefore, this analysis does not include announcements that were taken off the internet at the time of the data collection or before.
A brief cumulative statistics of these data can be summarized in the table below.
 
 

The facts are that:
-there were 42 unique CAC-2006 annoucements (8 international and 34 national );
-the announcements came from five continents: North America (3), South America (7), Europe (22, with Russia), Asia (Russia: 5) and Africa (2);
-the international announcement sites were physically located in the North America and Europe;
-all annoucements were in seven Indo-European languages: English (39), French (3), German (1), Norwegian (1), Portuguese (2), Russian (5) and Spanish (1);
-Brazil is the leader, what agrees with that the conference was hosted in this country and there were many Brazilian participants.

According to the final list of participants that were registered at the conferece, there were 136 participants from 23 countries. The geographical distribution of the participants is summarized in the table below. The countries are listed in decreasing and alphabetic order.

Country    No. Participants
----------------------------------
BRAZIL            63
USA               13
SPAIN             10
ARGENTINA          6
DENMARK            5
FINLAND            5
NETHERLANDS        5
PORTUGAL           5

CZECH REPUBLIC     1

GERMANY            1
IRAN               1
ITALY              1
JAPAN              1
MACEDONIA          1
NORWAY             1
----------------------------------
23 Countries     136 Participants
 

The facts are that:
-Brazil leas with almost half (46%) of participations, what is a good sign for chemometrics in this country and what justifies the choice of this country to host the confererence;
-the participants come from four continents: North America (17), South America (69), Europe (48) and Asia (2);
-most chemometric countries and regions are represented at the conferece: there are no many or none partipants from chemometrically active Australia, Asian South and East, and Eastern Europe.
 
 

Are the two data sets in the above tables correlated with each other? At a certain point, YES, they are correlated modestly (correlation coefficient is 0.421), as is shown in the figure below. There are countries that had online CAC's announcements but their researchers did not appear or appeared in a very small number (the bottom triangle). There are also countries with obviously more participants and no national CAC's announcements (the left triangle). These two classes disable that good correlation exists between the number of participants and the number of the announcements (the middle trapezoid).

How this plot was made? All the countries were taken into account from the both tables, and new countries from international annoucements that belong to companies were added (Slovenia and India), making in total 29 countries. First, the numbers of national annoucement sites was attributed to the corresponding countries. Then, to some countries one site more was added, knowing from before that these sites had existed (Finland, Germany, Portugal, Spain, Sweden and UK). The site for each international company was assigned as equal fraction to its member countries. The rest of the international sites that belonged to the world was assigned as equal fraction to each of the 29 countries. The final numbers were then transformed into log(x+1) form, where x was the number of sites or participants. Unfortunately, researchers that haven't appeared at the conference and had submitted their works previously, could not be taken into account.
