Cet ouvrage expose différentes façons de répondre à un des problèmes #statistiques les plus courants : la #régression.
La présentation témoigne d’un réel souci pédagogique. Les commandes permettant le traitement des exemples avec #python figurent dans le corps du texte. Enfin chaque chapitre est complété par une suite d’exercices.
Cet ouvrage s’adresse à des étudiants de Master et d’écoles d’ingénieurs ainsi qu’aux chercheurs en sciences appliquées.

#1: "Unceded” is a statement of fact, not an opinion.
#2: Lawfulness of a conflict is a statement of fact, not an opinion.
#3: Funny how there are lots of other "moral" arguments that are ok... but not this one.
#4: Diversity, equity and inclusion isn't a “doctrine”, it's simple kindess, get over yourselves probably-white-entitled-man-children-professors
The brain rot and fight against reason and empathy is coming to Canada. RESIST!!
"The petitioners want the court to order the university to stop declaring it's on unceded Indigenous land, from making statements on the morality or lawfulness of the Israeli-Palestinian conflict and from requiring job applicants to declare support for "diversity, equity and inclusion doctrines." "

Ich teile die Sorge und Verzweiflung, die Tracy Chapman im SPIEGEL-Interview äußert: »Da ich in den Siebzigerjahren aufgewachsen bin und von der Bürgerrechtsbewegung profitiert habe, zu einer Zeit, als sich die Dinge zum Besseren wandelten, hatte ich wohl die Erwartung, dass wir darauf weiter aufbauen würden.«
So kann man sich täuschen.

On #regression models #rstats:
1) cleaning method for test data has more impact than for train data
2) best performance does not require same cleaning process in both test and training data
3) regression models should should test several test cleaning pipelines.
PeerJ Computer ScienceThe effects of mismatched train and test data cleaning pipelines on regression models: lessons for practiceData quality problems are present in all real-world, large-scale datasets. Each of these potential problems can be addressed in multiple ways through data cleaning. However, there is no single best data cleaning approach that always produces a perfect result, meaning that a choice needs to be made about which approach to use. At the same time, machine learning (ML) models are being trained and tested on these cleaned datasets, usually with one single data cleaning pipeline applied. In practice, however, data cleaning pipelines are updated regularly, often without retraining of production models. It is therefore common to apply different test (or production) data than the data on which the models were originally trained. The changes in these new test data and the data cleaning process applied can have potential ramifications for model performance. In this article, we show the impact that altering a data cleaning pipeline between the training and testing steps of an ML workflow can have. Through the fitting and evaluation of over 6,000 models, we find that mismatches between cleaning pipelines on training and test data can have a meaningful impact on regression model performance. Counter-intuitively, such mismatches can improve test set performance and potentially alter model selection choices.

Regensburger Ermittlungsrichter ordnet DNA-Test an
„Einen solchen Beschluss hat ein Ermittlungsrichter am Amtsgericht Regensburg letzte Woche gegen eine 22-Jährige erlassen. Ohne vorherige Anhörung verfügte er, dass bei der jungen Frau ein sogenannter Mundhöhlenabstrich „und im Falle der Weigerung die Entnahme einer Blutprobe“ vorgenommen werden darf. Ebenso ordnete der Richter an, dass ihre Wohnung „zum Zweck der Entnahme von Körperzellen“ durchsucht werden darf. Dies stehe „in angemessenem Verhältnis zur Schwere der Tat“, heißt es in dem Beschluss…..“

Accuracy! To counter regression dilution, a method is to add a constraint on the statistical modeling.
Regression Redress restrains bias by segregating the residual values.

I mean, logically, it should have been easier to:
1. map the President's brain
2. intend to learn something from the map
3. progress to a more complex mapping of the brain of Drosophila melanogaster.
Pallab Ghosh (Science Correspondent, BBC) offers an eloquent description of the fruit fly:
"They can walk, hover and the males can even sing love songs to woo mates - all this with a brain that’s tinier than a pinhead."
It's alleged that funding for (1) was not forthcoming due to the previously acknowledged lack of connections between sparse neurons; the consequent likelihood of government-funded research finding nothing useful on the map.

Trump's federal Department of Health and Human Services and its agencies are purging its websites of information and data on a broad array of topics — from adolescent health to LGBTQ+ rights to HIV.
Several webpages from Centers for Disease Control and Prevention with references to LGBTQ+ health were no longer available. A page from the HHS Office for Civil Rights outlining the rights of LGBTQ+ people in health care settings was also gone as of Friday

Pearson's #correlation is irrelevant if you suspect that the relationship is not a straight line.
If monotonic relationship:
"#Spearman’s rho is particularly useful for small samples where weak correlations are expected, as it can detect subtle monotonic trends." It is "widespread across disciplines where the measurement precision is not guaranteed".
"#Kendall’s Tau-b is less affected [than Spearman’s rho] by outliers in the data, making it a robust option for datasets with extreme values."

A few days ago, the rsync package received important #security updates on several #Linux distributions. This update fixed serious and critical vulnerabilities.
Unfortunately the update also introduced a #regression, affecting scripts using rsync, including the widely used rsnapshot backup method.

In a shocking #accessibility #regression, the TescoGroceries website no longer uses headings to show products, either in search results or on shelves. Without headings, screen reader users like myself can no longer navigate on a per-product basis. We now have to move by focusable control, which provides a lengthy and inconsistent way around that we've not had to use for the last decade. This can mean pressing "tab" or similar up to 5 times per product before adding it to my basket, reducing my efficiency accordingly. It's 2025 and we're still seeing ridiculous and 100% avoidable barriers to something as simple as the weekly grocery shop as blind people. Someone should be held accountable for releasing stupid code.
