对。就是我质疑英国的这份研究。并且英政府已承认有误。有兴趣可读此贴。

该研究的Modeller过去的研究也非常离谱。被行内广泛质疑。见下文。

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.

政府只是说每天20万的感染是错误的建模预测吧,没有说研究有错。 -阿明.- 给 阿明. 发送悄悄话 (140 bytes) () 12/20/2021 postreply 14:51:18

原文也批评了该研究声称的Delta和Omicron住院率没有明显差别的说法。指出相差4倍。且统计上Significant。我计算 -value_hunter- 给 value_hunter 发送悄悄话 (499 bytes) () 12/20/2021 postreply 16:18:36

你用的是汇总的数据,他用的是回归分析,两者可以不一致。你仔细看数据,得O的年轻人的比重较高,而年轻人的住院率低,所以拉低了O的总 -skyline荷9- 给 skyline荷9 发送悄悄话 (553 bytes) () 12/20/2021 postreply 17:11:20

你算说到点子上了。我也有此猜疑。只是原文只提供了汇总数据。谢谢。 -value_hunter- 给 value_hunter 发送悄悄话 (0 bytes) () 12/20/2021 postreply 17:20:59

这有点像田横赛马,有选择性地比较,违背了统计最基本的原则 : 随机原则。 -LingYuan- 给 LingYuan 发送悄悄话 LingYuan 的博客首页 (0 bytes) () 12/20/2021 postreply 20:04:40

田忌赛马。嗯,现在不少都是选择性比较,统计也是,其结果会差很大甚至得出相悖结果。 -pickshell- 给 pickshell 发送悄悄话 (0 bytes) () 12/21/2021 postreply 06:17:53

他在混淆概念。同质之间的比较,怎么算做上士对下士。谁做统计不分组?难道将孩子与老人比? -fuz- 给 fuz 发送悄悄话 fuz 的博客首页 (0 bytes) () 12/21/2021 postreply 10:31:40
