How to generate normally distributed random variables on the Apple II microcomputerStarting from the well-known fuzzy k-means method, which was mainly intended for spherical clusters, several methods are consid
Let’s see how you can use R and ggplot to visualize boxplots. Make Your First ggplot Boxplot Data frame for Your Boxplot R has many datasets built-in, one of them being mtcars. It’s a small and easy-to-explore dataset we’ll use today to draw boxplots. You’ll need only gg...
in the density plot, the height of the plot at a given x-value corresponds to the “density” of the data. Ultimately, the shape of a density plot is very similar to a histogram of the same data, but the interpretation will be a...
Contrary to the traditional distribution of workloads, each data parallel rank does not have the complete model replica when the library’s tensor parallelism is used. Instead, each data parallel rank may have only a partition of the distributed modules, in addition to the entirety of the ...
The resulting weighted observations have analogous properties to a dataset collected through an RCT, and you can make inferences from them in many of the same ways you can for datasets collected through a designed experiment. Two common ways to estimate balancing weights are propensity scor...

Using Docker to deploy containers and microservices Debugging and troubleshooting, performance tuning, and practical ops tips This short review comes from this book or the store. Nginx HTTP Server Authors: Martin Fjordvald, Clement Nedelcu Harness the power of Nginx to make the most of your infrast...
In all cases, the basic approach for data transforms is the same. The heart of the RevoScaleR data step is a list oftransforms, each of which specifies an R expression to be evaluated. The data step typically is an assignment that either creates a new variable or modifies an existing varia...
Extra work was needed to clean the data and make the right correspondence. 4.1 Sample characterization 4.1.1 Demographics As can be seen in Table 2 and Fig. 1, the sample is composed mostly by Portuguese citizens (94%) of a varied age range, being the majority females (74%), adults ...
Next, we describe the data, and report the estimation results. We then use these results to assess the total effect of adding SKUs to the brand line, and decompose it along the different routes of influence. We do so for different types of introductions, and for customers with more or ...
