We take our whole family to lots of places because that's naturally the kind of family we are, none of us are huge homebodies and we all love visiting new and familiar places together and with people we love.  One of our parenting tools up our sleeves to keep our kids in check while we are out in the world is to remind the kids constantly about appropriate behavior in various zones.  Our technique is heavy on the front loading and takes a lot of practice and vigilance.  The kids get all the glory in the end ("your kids are so well behaved") with nearly no nod to all the behind-the-scenes work it took to get to that point...but that's parenting in a nutshell, amirite? So, our behavior zones parenting hack looks something like this - Every single time we are in the car traveling anywhere (literally, every single time and no matter where we are going) - before we arrive, we turn the radio down and one of us will say, "does everyone remember how we behave at ______....

A glimpse into what it is like to live in our home just this minute.     Intentional Outdoor Hours : 392+ hours (of 1000) Up 44 hours in the last two weeks which is pretty good, but I still need to push myself to grab as many hours as possible in these last few weeks of summer vacation. I got in outdoor time with dog walks, eating dinner outside (my summer fav!), and fires on the patio.  We got to have a long chat at our picnic table with cousin Heather while our kids went bonkers on the trampoline (which had been out of commission for the last month because I ordered the wrong size replacement mat!) Reading Bird by Bird by Anne Lamott and taking it so slow because every time I pick it up it is so thought provoking about the writing process that I need a few days to digest it and think about my own writing. So I also started Sisterland by Curtis Sittenfeld which I snagged off of my sweet friend Shelly and I'm enjoying it.  I continually am shocked each time the wri...

The spreadsheet is a valuable tool for data scientist. This is what the annual KDnuggets polls reveal during these last years where Excel spreadsheet is always well placed. In France, this popularity is largely confirmed by its almost systematic presence in job postings related to the data processing (statistics, data mining, data science, big data/data analytics, etc.). Excel is specifically referred, but this success must be viewed as an acknowledgment of the skills and capabilities of the spreadsheet tools. This tutorial is devoted to the Gnumeric Spreadsheet 1.12.12. It has interesting features: Setup and installation programs are small because it is not part of an office suite; It is fast and lightweight; It is dedicated to numerical computation and natively incorporates a "statistics" menu with the common statistical procedures (parametric tests, non-parametric tests, regression, principal component analysis, etc.); and, it seems more accurate than some popular spreads...

Hi, It seems that the failure has been resolved since yesterday "August 1st, 2017". Again, sorry for the inconvenience. I hope that the continuity of service will be ensured throughout the summer. Kind regards, Ricco (August 2nd, 2017).

Since a few days (since the 07/24/2017 approximately), the server of the Eric laboratory that hosts the Tanagra project files (software, books, course materials, tutorials...) is idle. After a power outage, there is nobody to restart the server during the summer period. And the server is located in a room in which I do not have access. So we wait. And it will take a little time, the summer break lasts a month, our University (and Lab) is officially reopened on August 21st! I am sorry for users that work from the documents that I put online. This difficulty is totally beyond my control and I cannot do anything about it. Some internet users are reported to me the problem. I take the initiative to inform you. As soon as the situation is back in order, I will let you know. Kind regards, Ricco (July 27th, 2017).

Interpretation of the clustering structure and the clusters is an essential step in unsupervised learning. Identifying the characteristics that underlie differentiation between groups allows to ensuring their credibility. In this course material, we explore the univariate and multivariate techniques. The first ones have the merit of the ease of calculation and reading, but do not take into account the joint effect of the variables. The seconds are a priori more efficient, but require additional expertise to fully understand the results.

Reading and finishing The Dry by Jane Harper .  Just like everyone else who has read it this year, I really enjoyed it and liked how I kinda knew all along what was going to happen but not enough that ...
