Why 2020 is a "magic year"

Sveriges nya dataportal
Sverige får nu en ny nationell dataportal med nytt namn och ny grafisk profil. Samtidigt blir det en ny webbadress, då öppnadata.se byts till dataportal.se. Lanseringen sker idag, men all funktionalitet finns inte på plats från start utan kommer att införas gradvis under 2020.

Statistics Canada expects move to the digital cloud will prompt some rumbling
Calgary HeraldStatistics Canada is planning to move its information holdings to the digital cloud — a shift the national number-crunching agency acknowledges will prompt questions about the protection of sensitive data.
The initiative is part of the federal government’s “cloud-first strategy” to meet the increasing demand for online services and provide an alternative to its own, increasingly creaky computers.

Enhancing Access to and Sharing of Data : Reconciling Risks and Benefits for Data Re-use across Societies
OECD iLibraryCurrent developments related to data-driven innovation, including in the context of the Internet of Things and artificial intelligence, have made data access and sharing more crucial than ever. Evidence presented in this report shows how enhancing access to and sharing of data (EASD) can help maximise the social and economic value of data re-use. It can increase the value of data to the data holder, and even more so to secondary data users, with additional positive spill-over benefits for country economies and society at large.

Debatten om opinionsmätningarna
Bakom lucka 9 i Politologernas julkalender finns en kommentar till debatten om opinionsmätningar, i synnerhet till @TorbjornNilsso:s artikel i förra veckan. Det fanns mer att tillägga, men jag valde att begränsa mig något. https://t.co/0VLoHJHfmt— Richard Öhrvall (@richardohrvall) December 9, 2019
Vad betyder egentligen ”varken bra eller dåligt”?
PolitologernaI enkätundersökningar är det ganska vanligt att de som svarar på enkäterna på vissa frågor får möjligheten att placera sig i mitten av en svarsskala med ojämnt antal svarsalternativ som är rangordnade, till exempel från bra till dåligt, från positivt till negativt, från mycket till litet eller liknande. Alternativet i mitten kallas ofta för skalans mittpunkt och svarsalternativet kan betecknas på olika sätt. I Sverige är det vanligt att mittpunkten betecknas med orden ”varken bra eller dåligt” om skalan går från bra till dåligt. Även alternativ som ”neutral” förekommer, liksom enbart siffror utan någon verbal etikett. Inom surveymetodforskningen kallas sådana skalor ofta för bipolära svarsskalor. Huruvida det är bra att erbjuda respondenterna en mittpunkt som svarsalternativ eller inte har debatterats länge inom forskningen och svaret beror i stort sett på vad enkätfrågan gäller.

5 Statistical Traps Data Scientists Should Avoid
Predictive Analytics Times - machine learning & data science newsFallacies are what we call the results of faulty reasoning. Statistical fallacies, a form of misuse of statistics, is poor statistical reasoning; you may have started off with sound data, but your use or interpretation of it, regardless of your possible purity of intent, has gone awry. Therefore, whatever decisions you base on these wrong moves will necessarily be incorrect.

Climate change: From the beginning, models have been remarkably accurate
VoxThe first systematic review finds that climate models have been remarkably accurate.
There are dozens of disciplines and subdisciplines within the broad ambit of climate science, studying everything from ancient geology to the spread of disease. But one discipline in particular is exposed to intense public scrutiny, the subject of long-running political and legal disputes: modeling.

Cathie Marsh Memorial Lecture - Wellbeing in policy: it’s all subjective
https://youtu.be/rydY43h5w_4
This talk considered the various ways in which subjective wellbeing can, and should, be measured for the purposes of informing policy decisions. It addressed some of the methodological challenges as well as issues surrounding the acceptability of using subjective reports of wellbeing to guide resource allocation decisions.
Speaker: Paul Dolan, Professor of Behavioural Science at the London School of Economics
Discussant: Nancy Hey, Director of the What Works Centre for Wellbeing

Why Data Mining is Still Important in 2019
Why Data Mining is Still Important in 2019The influence of technology on the world is constantly growing. In this new age where everything is being shifted to the online sphere, data has risen as the new currency. It has become the most important asset of every organization. Hence the uses of data mining in today’s world cannot be undermined or understated.
Data mining seems like magic to most people. Extreme accuracy and precision with the data loads are what make this highly powerful and as much intriguing. Data mining can be said to be an offshoot of the entire set of database technologies. It is a multi-pronged process that employs many elements from statistics like classification, regression, clustering and association. Additionally, many other non-statistical tasks are also an integral part of it. Earlier, going into the technical lanes that lead to data mining, let us take a short halt and try to arrive at its definition.

Flow‐dependent stochastic coupling for climate models with high ocean‐to‐atmosphere resolution ratio
Quarterly Journal of the Royal Meteorological Society - Wiley Online LibraryCurrent state‐of‐the‐art climate and also weather and seasonal forecast models represent the different climate subsystems, such as atmosphere, ocean, sea ice, and land surface, through a variety of modelling approaches. Different numerical methods are used to discretize these subsystems, which often require computational grids of a certain geometry. This often produces a climate model that is constructed from independent model components that are coupled at their respective interfaces (Valcke, 2013).

SCB tar betalt flera gånger

DEBATT. Sveriges företagare tvingas avsätta resurser för att ge underlag till SCB:s statistik. Det är inte rimligt att en revisor ska behöva anlitas för att svara på frågorna. Men när företag vill få analyser från SCB tar man betalt, och ibland flera gånger för samma uppdrag, skriver René Bongard och Erik Ageberg.

Why Should You Learn R for Data Science?
Analytics InsightData Science is the most popular field of study in today’s world that leverages scientific methods, processes, algorithms and systems to convert structured and unstructured data into meaningful insights. Since it is mostly comprised of statistics, R is the bridging language of this field. It is a popular programming language and software environment and an important tool for data science.
RSS welcomes new initiative to develop data science qualification
StatsLifeThe Royal Statistical Society welcomes a new project developing framework for a data science qualification at senior secondary school and introductory university level.
The International Data Science in Schools Project (IDSSP) Curriculum Framework has brought together international communities - from the USA, Canada, Australia, New Zealand and the UK - in statistics and computer science, to develop an ambitious framework for the standalone qualification in data science.
