PRESIDENT’S COLUMN

The use of the O.C.E.A.N model and Big Data

The use of Big Data is becoming increasingly evident in the world around us. It was even

used in the recent elections held in the USA which resulted in the startling outcome of Donald

Trump becoming the new president. The company behind Trump’s online campaign was

Cambridge Analytica ― a Big Data firm. This is according to an article published by Hannes

Grassegger and Mikael Krogerus entitled: “The data that turned the world upside down”. The

article appeared in 2016 in Das Magazin, a respected German magazine. An English

translation of their article (a very interesting read) can be found at

https://motherboard.vice.com/en_us/article/how-our-likes-helped-trump-win. I give a short

summary here.

Cambridge Analytica used a psychometric model that measure five psychological traits of

personality. The model is known as O.C.E.A.N. which is an acronym for the personality traits

of Openness (how open are you to new experiences?), Conscientiousness (how much of a

perfectionist are you?), Extroversion (how sociable are you?), Agreeableness (how

considerate and cooperative are you?) and Neuroticism (how sensitive are you?). Measures

of these traits were collected from people who completed online personality tests. These

measures were then correlated with demographic variables such as gender, age and

location, as well as the person’s online behaviour, such as what the person “liked”, shared

prerequisite for the user taking the personality test).

for good or for bad.

Spotlight on Prof Nico Laubsher

Nico Francois Laubscher was born in Paarl, 1934. His childhood was spent on a farm near

the small town of Tadcaster at Vaalhartz in the Northern Cape, where he matriculated in 1951

at the Vaalhartz High School. Between 1952 and 1960 he studied at Potchefstroom

University, completing BSc (Applied Mathematics), BSc (Hons) (Mathematics), MSc

(Mathematics) and in 1960 DSc (Mathematical Statistics). His supervisors were HS Steyn

and JM de Wet. His dissertation was titled "On transformations for the stabilization of

variance and the normalization of distribution functions".

Feedback on the 4th African International Conference on Statistics

Left: Discussions during the poster session. Middle: Dr Barry Nussbaum

(President of the American Statistical Association) giving his address.

Right: Awarding of prizes during the gala dinner

The 4th African International Conference on Statistics was hosted on 20-23

March 2017 by the University of Limpopo in collaboration with the University of

Maryland Baltimore County (UMBC), USA. The conference was held at The

Ranch Resort just outside Polokwane with the central theme being “New

Methods of Data Analysis & Statistical Applications to Big Data”.

The conference had a wealth of international experts that presented keynote

addresses during the 4-day conference. As chief guest, Dr. Barry Nussbaum -

President of the American Statistical Association - delighted the delegates with

his very interesting address titled “It’s Not What We Said, It’s Not What They

Heard, It’s What They Say They Heard”. As main argument, he highlighted the

importance of conveying clear and understandable messages to any audience

based on thorough statistical analyses. In addition to Dr Nussbaum, 21 other

international experts (from the USA, Canada, Hong Kong, Cameroon, Portugal,

Germany, Belgium and the Philippines) gave keynote addresses during this

thought-provoking conference.

An important panel discussion took place (led by Dr. Malick Mbodj from the

Bowie State University, USA) regarding the retention of African Statisticians in

Africa. The focus of the discussion centred on establishing greater collaboration

between African and international universities in terms of the training of

statisticians on tertiary level. It was agreed that Dr. Mbodj, Prof. Yehenew Kifle

(University of Limpopo) and Prof. Loyiso Nongxa (Wits/NRF) will be the driving

forces of this initiative.

During a splendid gala dinner, a number of prizes were awarded to the student

poster competition winners, sponsored by SAS and the UMBC. Furthermore, Dr

Sinha (UMBC) entertained the delegates with a few (more) card tricks and too

soon it was time to say farewell to all the delegates and the plethora of

international experts.

The 4th African International Conference on Statistics was a great success and

presented an exceptional opportunity to rub shoulders with distinguished

international Statisticians. It is highly recommended that SASA members should

attend the 5th African International Conference on Statistics. We hope to see

many SASA members there.

The seventieth anniversary of the Department of Statistics and Actuarial Science at the

University of Stellenbosch was celebrated on Saturday, 26 November 2016. It was a beautiful

spring day in Stellenbosch. The seminar covered technical and popular topics which were

presented by young, well- known alumni of the Department, as well as international

academics with a South African connection. About 100 alumni, staff, colleagues from

Universities in South Africa and abroad, donors and friends of the Department attended the

festivities.

Stefan Britz is a promising young statistician employed at the University of Cape Town. He

teaches Statistics at various levels and he is supervising postgraduate students with

interesting research questions, ranging from cricket research to statistics in forensics. Stefan

is a proud member of SASA; he was the brains behind the pub quiz at the most recent SASA

conference. I recently had the opportunity to ask him some questions relating to his career;

read about his passion for stats.
