The geometry of forecast reconciliation

2021-09-16
Talk given at Macquarie University, Sydney (28 August 2020) and City University of Hong Kong (16 September 2021) It is common to forecast at different levels of aggregation. For example, a retail company will want national forecasts, state forecasts, and store-level forecasts. And they will want them for all products, for groups of products, and for individual products. Forecast reconciliation methods allow for the forecasts at all levels of aggregation to be adjusted so they are consistent with each …

简单的异速缩放3基于单一物种的异速缩放

2021-09-16
前言： 由动物数据外推人体药代动力学参数（下文简称为“外推”）是药物开发的重要工具。异速缩放是外推方法中的一种，该方法拥有许多支持者，并且基于异速缩放，人们已经提出了许多不同的方法和技术来优化从动物到人类的药代动力学参数的预测。 除了自己基于多物种的数据估算出异速缩放的方程中的参数然后开展其他物种数据的预测外，有时常常由于物种数据有限，不得不将将异速缩放的方程中的参数预先指定，然后开展其他物种的预测，本文介绍了“基于单一物种”+“预先指定缩放系数”的方法进行异速缩放预测。 目录 一、异速缩放公式 对数尺度 𝐿𝑛(𝑃𝑎𝑟𝑎𝑚𝑒𝑡𝑒𝑟)=𝐿𝑛(𝑖𝑛𝑡)+𝑏𝑒𝑡𝑎∗𝐿𝑛(𝑊𝑒𝑖𝑔ℎ𝑡) 常数尺度 𝑃𝑎𝑟𝑎𝑚𝑒𝑡𝑒𝑟=𝑖𝑛𝑡∗𝑊𝑒𝑖𝑔ℎ𝑡^𝑏𝑒𝑡𝑎 其中: int→截距 beta→斜率→缩放系数 二、异速缩放的一种特殊 …

Reassessing Nate Silver’s claim from last month that Democrats’ successful (in retrospect) 1-and-Done campaign against the California recall was “self-destructive . . . bad advice . . . a mistake”

2021-09-16
Roy shared this take from political consultant Nate Silver last month: It’s self-destructive more than self-interested. Pretty decent chance Newsom gets recalled. Democrats could potentially keep the seat if they urged their voters to consolidate behind an alternative Democrat but instead they’re telling them not to vote on the replacement! Silver was referring to the …

BREAKING: Benford’s law violations in California. Hollywood TV and movie franchises got some splainin to do!

2021-09-16
As you may have heard, there was MASSIVE FRAUD in the California election a couple days ago. Something like 4 million illegal votes, lots of dead people voting, mysterious suitcase, the whole deal. Maybe Ted Cruz will investigate. He could ask the attorney general of Texas to look into it and hire Mary Rosh and …

This post is by Phil Price, not Andrew. Andrew wrote a post back on September 2 that plugged a piece by Jon Zelner, Nina Masters, Ramya Naraharisetti, Sanyu Mojola, and Merlin Chowkwanyun about complexities of pandemic modeling. In the comments, someone who calls himself Anoneuoid said (referring to model projections compiled and summarized by the …
