稍微对互联网A/B testing有一点了解的同学们应该都清楚,做A/B testing的时候希望把每一个用户随机分配到试验组(treatment group)和控制组(control group)。 今天在这篇文章里,想简单聊聊,为什么我们要做随机分配(why we need to do random assignment),和应该怎么做随机分配(how to do random assignment)。 --...
在互联网领域，A/B测试是不可或缺的工具之一。在进行A/B测试时，重要的一环便是随机分配（Random Assignment），这是为何和如何进行随机分配的探讨。首先，理解为何需要随机分配至关重要。这源于因果推断(Causal Inference)中的反事实模型(Counterfactual Model)。设想一组用户，随机分配到试验组和控制组，...
Random assignment to experimental conditions has been taken to be a gold-standard technique for establishing causality. Despite this, it is unclear how often random assignment fails to eliminate non-trivial differences between experimental conditions. Further, it is unknown to what extent larger sample...
View the client deployment and assignment reports to track client installation progress. Additionally, the client log files provide more detailed information for troubleshooting and do not require the installation of a fallback status point. For example, the CCM.log file on the site server records ...

enabling the port & pin, and switch it to the correct peripheral mode (I2C in this case). In the LPCXpresso SDK, this is done in a file called pin_mux.c. Check those are correct for your MCU and your board, cross-referencing with the datasheet (port/pin assignment).For test ...
As a language for statistical analysis, R has a comprehensive library of functions for generating random numbers from various statistical distributions. In this post, I want to focus on the simplest of questions: How do I generate a random number? The an
Because a block device’s total size is fixed and easy to index, processes have random access to any block in the device with the help of the kernel. 程序以固定的块大小从块设备中访问数据。 上述示例中的sda1是一个磁盘设备,也是一种块设备。 磁盘可以被分割成数据块。 由于块设备的总大小是...
