對。就是我質疑英國的這份研究。並且英政府已承認有誤。有興趣可讀此貼。

該研究的Modeller過去的研究也非常離譜。被行內廣泛質疑。見下文。

Who is Neil Ferguson, the Imperial College London virus modeller and Government scientific adviser

Prof Ferguson has been a key figure around the Government's scientific community for years

 

Neil Ferguson

Whenever Government ministers have been put in a sticky spot over their approach to their coronavirus pandemic their answer has always been the same: they are just following the science.

And by "following the science" they have often meant adhering to the advice of Neil Ferguson, the virus modeller from Imperial College London and a scientific adviser to the Government for 20 years.

It was his team's forecast, on March 16, of 500,000 deaths from the coronavirus pandemic if no action was taken which is largely credited with convincing the Government to change course and impose the lockdown on Britain which could last a year.

Prof Ferguson, who is based in the faculty of medicine at Imperial's School of Public Health, has been a key figure around the Government's scientific community for years.

He was awarded an OBE by the Queen for his modelling work on the spread of foot and mouth among cattle in 2001, which suggested that the culling of animals should include not only those found to be infected with the virus but also those on adjacent farms, even if there was no physical evidence of infection.

The advice helped to persuade Tony Blair’s government to carry out a widespread pre-emptive culling which ultimately led to the deaths of more than six million cattle, sheep and pigs. The cost to the economy was later estimated at £10 billion.

But a report in 2011 stated Prof Ferguson’s models made a “serious error” by “ignoring the species composition of farms,” and the fact that the disease spread faster between some species than others.

Prof Ferguson also played a prominent role in producing mathematical models for the swine flu pandemic in 2009 and the Ebola outbreak in 2014.

There was more controversy when his team's swine flu models predicted a scenario in which 65,000 people in the UK died – a significant benchmark in the WHO's decision to issue a pandemic. In the end, the UK death toll from swine flu stood at 457.

He also predicted that up to 50,000 people could die from ‘mad cow disease’. To date there have been only 177 deaths from the human form of BSE.

The scientist has robustly defended his work, saying that he had worked with limited data and limited time so the models weren’t 100 per cent right – but that the conclusions it reached were valid. 

The academic, 51, was born in Cumbria. His father was an educational psychologist, while his mother was a librarian who later became an Anglican priest.

He moved to Wales, and was educated at Llanidoes High School and then Lady Margaret Hall, Oxford University.  Prof Ferguson is married with a wife and child, who live apart from him. It is understood the couple are estranged.

政府隻是說每天20萬的感染是錯誤的建模預測吧,沒有說研究有錯。 -阿明.- 給 阿明. 發送悄悄話 (140 bytes) () 12/20/2021 postreply 14:51:18

原文也批評了該研究聲稱的Delta和Omicron住院率沒有明顯差別的說法。指出相差4倍。且統計上Significant。我計算 -value_hunter- 給 value_hunter 發送悄悄話 (499 bytes) () 12/20/2021 postreply 16:18:36

你用的是匯總的數據,他用的是回歸分析,兩者可以不一致。你仔細看數據,得O的年輕人的比重較高,而年輕人的住院率低,所以拉低了O的總 -skyline荷9- 給 skyline荷9 發送悄悄話 (553 bytes) () 12/20/2021 postreply 17:11:20

你算說到點子上了。我也有此猜疑。隻是原文隻提供了匯總數據。謝謝。 -value_hunter- 給 value_hunter 發送悄悄話 (0 bytes) () 12/20/2021 postreply 17:20:59

這有點像田橫賽馬,有選擇性地比較,違背了統計最基本的原則 : 隨機原則。 -LingYuan- 給 LingYuan 發送悄悄話 LingYuan 的博客首頁 (0 bytes) () 12/20/2021 postreply 20:04:40

田忌賽馬。嗯,現在不少都是選擇性比較,統計也是,其結果會差很大甚至得出相悖結果。 -pickshell- 給 pickshell 發送悄悄話 (0 bytes) () 12/21/2021 postreply 06:17:53

他在混淆概念。同質之間的比較,怎麽算做上士對下士。誰做統計不分組?難道將孩子與老人比? -fuz- 給 fuz 發送悄悄話 fuz 的博客首頁 (0 bytes) () 12/21/2021 postreply 10:31:40
