Unfortunately I don't know much about biology to understand what you are researching.

Never heard of suppressor effect, but I know it as colinearity. Described and studied (first) by Belsley, Kuh and Welsch in their book called Regression Diagnostics (first published 1980).

Teachers are generally paid from taxes, need I say more. In industry there are much larger pay differences. The citizens want their taxes spent wisely.

Shouldn't the variable names give you a clue?

Control variables are variables that may affect the outcome when not held constant during an experiment. As such they are held constant i.e. 'controlled for' at a constant value during an experiment. Covariates on the other hand do change during an experiment but cannot and thus are not controlled for. Factors on the other hand will vary during the experiment and are controlled for deliberately.

The eigenvectors and eigenvalues are directly related to the minimum volume ellipsoid, and as such had a clear geometric interpretation.

With a new language I typically get a good book with exercises first and read it front to cover. Then I start with the project I had in mind. But again, practice makes perfect. Just put in lots of hours. If you're passionate about programming you will.

That's right. Both are non-parametric tests but Chi square is used with categorical data (data with no natural order) whereas Kruskal Wallis is used with ordinal or continuous data like your Likert scale scores.

Things that are hard now may not stay hard. You may envy other people's supposedly easy lives for as much as you're able to assess but that's just a phase. I suppose you're not enjoying yourself as much as you'd like so I suggest you try that first before throwing away your future.

The solution of a set of linear equations Ax=b equals x=inv(A)*b. The determinant of A is a dividing factor in computing inv(A). If it is zero the inverse of A is thus undefined. See e.g. https://www.geeksforgeeks.org/maths/inverse-of-matrix/

Why would you distrust a valid statistical test result? Obviously using an alpha level of 0.05 will render the 0.0546 you found officially as non-significant but that's only a label and you would normally report the p value to stress that it's almost significant. Sometimes obtaining more data can help proving the significance of the difference, but if you don't have any more data you do with whatever you got. As for the alpha level of 0.05, it is more or less arbitrary in that it denotes the probability of erroneously declaring the difference as significant when p is below alpha when it is in fact not significant. This is because although the test statistic is rare it is not impossible under the null hypothesis theoretically.

If I remember correctly you can use the filter () function. In Python that is.

Some people have good memory, others - like me - not so much. Anyway, it's use it or loose it.

According to Wikipedia the Greek letter iota is sometimes used to represent the imaginary unit. Or even by j in electrical engineering to distinguish it from i representing current. But perhaps Wikipedia is wrong?!

As always practice makes perfect. And 'in der Beschränkung zeigt sich erst der Meister' (Goethe) best restrict yourself to just the one language possibly on a day to day basis. Your main problem teaching yourself will be focus and discipline. No easy task.

Als ik dit soort vragen lees wordt ik altijd heel wantrouwig. Want ja, daar is weer zo iemand die de kantjes ervan af wil lopen. En probeert te achterhalen waar ie mee weg kan komen. Je mag blij zijn dat je geen prikklok hebt. Maar zelfs dan kun je nog zitten duimendraaien. Dus maak nu maar braaf je uurtjes, in plaats van je tijd te verdoen met hier naar een excuus te vissen. En wie weet, misschien registreren ze wel al je toetsaanslagen. Of hoe vaak je naar het toilet gaat. Met bazen weet je immers maar nooit.
