Our democracy is not self-executing. It depends on us all as citizens, regardless of our political affiliations, to stand up and fight for the core values that have made this country the envy of the world.

R is crazy for automating business analytics AND data science in Excel.

Let's dive in:

[Joachim Schork @JoachimSchork]

Unlocking the full potential of your linear regression analysis starts with validating its suitability. Here’s a summary of how to validate assumptions before applying this model:

1️⃣ Linearity: The relationship between predictors (independent variables) and the response (dependent variable) should be linear. Think of a car traveling at a constant speed: the distance traveled increases proportionally with time.

2️⃣ Independence: Residuals (errors) must be independent of each other. Picture students taking an exam in separate rooms without communication. Each student's score is independent of the others.

3️⃣ Homoscedasticity vs. Heteroscedasticity: Residuals should have a constant spread across all levels of the independent variable. If the variability changes, like scores varying differently for easy versus hard exam questions, it indicates heteroscedasticity, which is problematic.

4️⃣ Normality of Residuals (Multivariate Normality): Residuals should follow a normal distribution, similar to the bell curve seen when rolling a fair die many times.

5️⃣ No Multicollinearity: Independent variables should not be highly correlated with each other. Imagine assessing the impact of both age and experience on salary: if they move together, it’s hard to distinguish their individual effects.

6️⃣ Measurement Error: Measurement errors can lead to unreliable predictions. It’s like weighing fruits on a scale that occasionally gives wrong readings.

Type 1 and Type 2 errors are confusing.

Choosing the right statistical test can be tricky. 

Some tests seem ideal but don’t fit all data types.

You don't have to worry anymore.

Ukraine and Russia were close to a peace deal in spring 2022 but Ukraine rejected it?

This is one of the favorite lies promoted by Russia and its sympathisers to shift the focus… and blame.

However, a closer look at the facts reveals that the whole story does not hold water.

Last Monday ended the annual conference of #PhD students in Food #Science held in #Parma. Lots of ideas, results a smiles.
See you next year. 🧑🏿‍🔬👩‍🔬🧑‍🔬🧑🏾‍🔬

[Luca Bettera @BetteraLuca]

A wonderful experience!

[Agroscope @agroscope]

A great success! Organised for the first time in #Switzerland, the #FACEnetwork European artisan #cheese producers’ congress brought together over 200 participants from 15 countries, from 11 to 13 October in Grangeneuve. The theme of this congress: #RawMilk and raw-milk products.
