COVID19 Cases #1 – Latest Data and Trends for England

By

Last updated on 27th September 2020 but downloadable spreadsheet in section 3a was updated on 19th October 2020.  I will update the post when I get the time!

The latest data for COVID19 (Coronavirus) cases in England as of Saturday 26th September 2020 shows the number of people testing positive for COVID19 is up 60% from a week ago but this masks extreme regional disparities that make the national trend meaningless.  The North is in the grip of a second wave unlike the South which is not.  Unless recent trends in the North abate, the scenario of 50k positive tests per day by the end of October recently postulated by the Chief Scientific Officer remains feasible.

Pay Gap Case Study #4 – What is the gender pay gap at Novartis UK?

By

Welcome to my next case study where I look at the 2019 pay gap figures of Novartis UK.  They caught my eye when they posted on LinkedIn the following statement.

“… our 2019 gender pay report which highlights that on average, women earn more than men across all of our UK sites and divisions…“

When I looked at the two legal entities that were required to report gender pay gaps, I saw that both reported pay gaps favouring men instead.  Something odd is going here and it’s a perfect case study to show why anyone who analyses pay gaps needs to pay more attention to a Bletchley Park codebreaker from world war 2 who introduced the world to Simpson’s Paradox.

COVID19 Deaths #2 – Are Public Health England’s Figures Misleading?

By

During the first wave of the COVID19 epidemic, the daily number of deaths published by Public Health England (PHE) has been the main headline in the news.  On 17th July, Matt Hancock, Secretary of State for Health, called for a review of this time series after a blog published by Yoon Loke & Carl Heneghan of Oxford University questioned whether definition used by this time series was appropriate.  I myself had noticed a change in the PHEr time series in my tracker of COVID19 deaths in England but I hadn’t understood why this might have been the case.  After looking at the data again in more detail, I have concluded that this time series is overestimating the number of deaths by 42 +/- 13 per day since the 23rd May and it needs to be revised otherwise it will create confusion should a second wave come.

Last updated on 25th July 2020 – future updates will be infrequent.

The latest data for deaths due to COVID19 (Coronavirus) in England as of Friday 24th July 2020 show that the first wave of the pandemic is now over when one looks as excess deaths.  People will still be dying of COVID19 for weeks yet but the overall number of excess deaths is now negative.

COVID19 Deaths #2H – Estimated Excess Deaths in England up to 26th June

In many countries across the world, the total effect of the Coronavirus pandemic is now being measured using the concept of Excess Deaths.  However, publication of such data by the Office of National Statistics for England is up to 2 weeks slower than the daily deaths published by Public Health England.  In this post, I update my model which uses the PHE series to estimate what the ONS will publish for excess deaths in England on Tuesday 30th June.
