The R Trader » Blog Archive » BERT: a newcomer in the R Excel connection A few months ago a reader point me out this new way of connecting R and Excel. I don’t know for how long this has been around, but I never came across it and I’ve never seen any blog post or article about it. So I decided to write a post as the tool is really worth it and before anyone asks, I’m not related to the company in any way. BERT stands for Basic Excel R Toolkit. It’s free (licensed under the GPL v2) and it has been developed by Structured Data LLC. At the time of writing the current version of BERT is 1.07. List of academic databases and search engines Wikipedia list article This page contains a representative list of notable databases and search engines useful in an academic setting for finding and accessing articles in academic journals, institutional repositories, archives, or other collections of scientific and other articles. Databases and search engines differ substantially in terms of coverage and retrieval qualities. Users need to account for qualities and limitations of databases and search engines, especially those searching systematically for records such as in systematic reviews or meta-analyses.[1] As the distinction between a database and a search engine is unclear for these complex document retrieval systems, see:

"The egg" - Page 11 You were on your way home when you died. It was a car accident. Nothing particularly remarkable, but fatal nonetheless. You left behind a wife and two children. It was a painless death. The EMTs tried their best to save you, but to no avail. Five Data Science Projects To Get You Started Nothing beats the learning which happens on the job! Whether it is the challenges you face while collecting the data or cleaning it up, you can only appreciate the efforts, once you have undergone the process. Hence, the best way to learn Data Science is to do Data Science. There is no substitute to it.

Dismal Scientist Relevant, easy-to-understand global economic information in real time "Fifteen minutes with Dismal saves you three hours..." Pete Gioia 10 Psychological Experiments That Went Horribly Wrong Psychology as we know it is a relatively young science, but since its inception it has helped us to gain a greater understanding of ourselves and our interactions with the world. Many psychological experiments have been valid and ethical, allowing researchers to make new treatments and therapies available, and giving other insights into our motivations and actions. Sadly, others have ended up backfiring horribly — ruining lives and shaming the profession. Here are ten psychological experiments that spiraled out of control. 10.

K-Nearest Neighbors Introduction K-Nearest Neighbor is a also knowns as lzay learning classifier. Decision tree and rule-based classifiers are designed to learn a model that maps the input attributes to the class lable as soon as the training data becomes available, and thus they are known as eager learning classifiers. How Secure Is My Password? Entries are 100% secure and not stored in any way or shared with anyone. Period. As Seen On Creating and maintaining secure passwords can definitely be a hassle. One of the main reasons for creating this tool is to check to make sure you don’t get stuck in a rut using passwords that are easily cracked but rather, are using the best online password strategies.

Introduction to Principal Component Analysis (PCA) - Laura Diane Hamilton Principal Component Analysis (PCA) is a dimensionality-reduction technique that is often used to transform a high-dimensional dataset into a smaller-dimensional subspace prior to running a machine learning algorithm on the data. When should you use PCA? It is often helpful to use a dimensionality-reduction technique such as PCA prior to performing machine learning because: Statistical Sites on the World Wide Web Skip to Content US Department of Labor A to Z Index | FAQs | About BLS | Contact Us U.S. Bureau of Labor Statistics Follow Us Need Some Motivation Right Now?
