Flooding has been in the news the past few days, and that makes me want to analyze some data! I hang out at Jordan Lake (here in central North Carolina) a lot, so I decided to download the data for that lake, and do a graphical analysis. If you're interested
Wie schon gesagt, ich bin Gamer. Ich bin außerdem Freizeit-Spieleentwickler und Angestellter. Es ist also nicht weiter verwunderlich, dass Gamification (ich möchte hier bei der englischen Schreibweise bleiben) ein interessantes Thema für mich ist. Gemeint ist damit die Übertragung von Techniken, die üblicherweise in Spielen eingesetzt werden, auf andere Bereiche,
An analyst was using SAS to analyze some data from an experiment. He noticed that the response variable is always positive (such as volume, size, or weight), but his statistical model predicts some negative responses. He posted the data and asked if it is possible to modify the graph so
We are in the midst of our third Powerful Tools of Caregiver class offering, and I am reminded again of the importance of self care for caregivers. As primary caregivers, it is likely you will experience higher degrees of stress, exhaustion, and are more prone to illness. It is important
Según las últimas cifras entregadas por el Foro Económico Mundial en 2018, a diario, 2.000 millones de personas –cerca de la tercera parte de la población del planeta- hacen uso de los productos de una sola compañía global de consumo. Y es, precisamente, en el desarrollo de esa dinámica donde
Here in the US, there's a lot of talk about the flu each year. First, people discuss whether or not to get the flu shot. Then there are discussions about whether or not you or your friends have the flu (or something else). Then the discussions about what strain of
„Die wichtigsten Dinge schreibt man am besten gleich in die Einleitung! Eventuell lesen einige ja gar nicht bis zum Hauptteil weiter“. Einen ähnlichen Gedanken hatte ich bei meinem aktuellen Buch Applying Data Science – Business Case Studies Using SAS auch. Da sind bereits in der Einleitung die Mehrwerte aufgezählt, die
Statisticians often emphasize the dangers of extrapolating from a univariate regression model. A common exercise in introductory statistics is to ask students to compute a model of population growth and predict the population far in the future. The students learn that extrapolating from a model can result in a nonsensical
SAS makes it easy for you to create a large amount of procedure output with very few statements. However, when you create a large amount of procedure output with the Output Delivery System (ODS), your SAS session might stop responding or run slowly. In some cases, SAS generates a “Not
This is the fifth and final post in my series of posts about the deep learning model I developed to detect tumors in 3D CT scans of livers. My last post talked about visualizing the results of the computer vision project. This post will cover model accuracy and the final
Nous voulons mener des actions et mesurer leur impact - de manière scientifique. Pour évaluer la vitesse moyenne (d'une voiture) à mi-chemin d'une distance donnée, nous devrions marquer le point médian et utiliser un chronomètre. Pour mesurer la conversion générée par un catalogue imprimé et la comparer à celle d'un
Las estadísticas demuestran que para más de 2/3 partes de nuestros clientes, el momento de mayor preocupación es el de la transición, es decir, cuando tienen que pasar la información de sus servidores a la nube. Se podría decir que se encuentra en el primer lugar de nuestro ranking de
US farmers grow a lot of food ... but did you know some of them also grow fuel for our vehicles? Follow along and you'll learn how much fuel they grow, and also learn some tips about plotting this type of data! These days most gasoline in the US has
I am obsessed with jigsaw puzzles. Specifically, 1000-piece mystery puzzles, entertaining not just for their pictorial humor, but also for the challenge. Unlike traditional puzzles, you don't know what you are putting together because the completed puzzle isn't pictured on the box. Mystery puzzles are constructed so that you must
I look forward to Pi Day every year at SAS because it's a day of celebration including yummy pies and challenging games that challenge you to recall the digits after the decimal point in Pi. Plus you get to wear Pi t-shirts (I have about seven). Today, though we are going to talk about DLPy which sounds like Pi and
