TL;DR: Tried the ID4, Ioniq 5 2WD, and Model Y LR. Settled on the Model Y because it:

• offered the most space of the three
• had the most range and efficiency of the three (and included a heat pump, which really should be standard in all EVs in that price class)
• felt the nicest to drive despite the bumpy suspension; the one-pedal driving was notably smoother (especially compared to the rather jerky Ioniq 5)
• had a much better software experience (compared to the almost unusable system in the ID4 & the rather cluttered UI of the Ioniq) albeit with some notable frustrations,
• benefits from the supercharger network for which we don’t need membership cards or any such nonsense; we can simply plug and go.

We are in the market for an EV. We will use the car that we buy so long as it can be used, and we have a specific set of priorities. We test drove three cars over the past month. I’m posting my impressions not just in the hope that it might help someone else out (like reading so many of your posts has helped me out), but also to consolidate my thoughts and perhaps even get some additional perspectives/opinions/insights. I may edit this to add / clarify things as I go along. This is an extremely long, potentially rambly post; you have been warned.

Budget:

We are in Austria; our budget is capped at €60,000 including:

• The car plus any addons/
• Incentives (€5,000 from the country, €2,000 from the state we are in)
• Registration costs & related overheads (estimating these at €1,500ish)
• A home charging station (assuming this to be €1,000ish)
• One year of complete cover insurance (estimating this at €2,000ish; it’s essential for financing)

Priorities:

The most important requirement is space & practicality. Our bare minimum expectation is that the car must comfortably fit two to three adults, one (yet to come) medium sized dog (25 – 35 kg) with its crate, and luggage for a week-long trip. Ideally, we would like the car to up to fit four adults, up to two dogs, and luggage (which may or may not include ski-gear; we will get a roof rack, naturally). This car will be used for hauling stuff, people, pets, and any combination of those three.

Range, efficiency & charging possibilities are next. I don’t necessarily have “range anxiety” and I certainly don’t intend to drive 600 km in one stretch on the regular; I usually take a break every 200 to 300 km and stopping periodically will be normal once we start tra

Hi, I'm a college student. I recently learned after satisfying some assumptions, coefficient of slope could be written as, i.e. beta_hat~N( beta , var(beta_hat) ). Then, it could be converted to the form of (beta_hat - beta)/sd(beta_hat). I read the textbook. It mentioned we need to replace sd into se to find t-statistics and doing a null hypothesis test.

However, I'm wondering what the notation should we gives to the sd(beta_hat)?. I saw some people use the symbol σ. Is this appropriate? Because I was thinking beta_hat is a sample estimation, and it's akward to use the the standard deviation symbol in population parameter for a symbol in sample parameter. Shouldn't we use s insted of σ? And when we are doing a estimate to this sd, we can say s_hat.

What's the symbol for standard deviation for slope coefficient and standard error for slope coefficient?

It would be appreciated if someone could give me some hints!

The text is Koller and Friedman. P|=(A_|_B) has previously been used in the text to denote independence of the event/ random variable A from B. I_l(H) denotes the local independencies of a Markov network H, while I_p(H) denotes the pairwise independencies. It was previously stated that I_p(H) is weaker than I_l(H)

E: Does it perhaps mean that given these independencies observable from the graph H, if a probability distribution on the graph satisfies the definition of independence for the variables in the elements of I_l(H), it will do the same for I_p(H)?

I am Dr. Ellie Murray, assistant professor of epidemiology at Boston University School of Public Health and simulation modeling researcher at the Hariri Institute for Computing. I research the control of disease patterns in human populations. Specifically, my work uses simulations to study and improve evidence-based decision-making by patients, clinicians, and policy makers. In the past year, I have zeroed in on understanding responses to COVID-19 and suggesting safe, long-term options to combat pandemic fatigue. Now, I'm working with other researchers in a Focused Research Program to estimate the effects of public health decisions using simulation modeling.

Ask me anything about:

Where can I find the most accurate, up-to-date information on COVID-19?

Do I need a booster shot of the COVID-19 vaccine?

Should I be wearing a mask indoors? Outside?

How do public health officials make decisions on vaccine boosters, mask mandates, and other policies?

What is simulation modeling?

How can a simulation tell us anything about real life?

How do epidemiologists use simulations to understand the spread?

I’m seeing a lot of people confused about a recent post talking about a chord progression, so I think this would be a good time to explain some very basics of music theory, particularly harmony. Remember, there are no hard rules, this is mostly just a way of describing music and communicating with others.

First, most western music is tonal, meaning that it uses collections of notes called scales and the relationship between notes is important. The two most common types of scales are known as major and (natural) minor, and have 7 notes in them. The first note of each scale is called the tonic, and you can use any note as your first one. To simplify, I’ll just use the two easiest ones: C Major and A (natural) minor. On a keyboard, starting on C and only playing white keys, you get C Major scale (C D E F G A B). Starting on A and only playing white keys, you get A minor scale (A B C D E F G). Play them if you can (or program them on the piano roll of your DAW) and see how different their sounds are, even though you are playing the same keys.

Now, if we number the notes on the scale from 1 to 7, we get the scale degree of that note. So on C Major (C-1 D-2 E-3 F-4 G-5 A-6 B-7), E is the 3rd degree, and G is the fifth. For each of those degrees we can form a type of chord called a triad: pick three alternating notes of the scale and play them together. So on the first degree we have the C-E-G triad, and on the sixth degree we have the A-C-E triad (we wrap around the scale when we get to the end). Each triad can be named by the bottom note and its quality (major, minor, diminished). To figure out the quality, we check how many piano keys are between the first and second note of the triad [Edit: we are counting keys to keep it simple, not semitones]. If there are 5 keys, it’s major (eg C to E has C C# D D# and E); if there are 4 keys, it’s minor (eg A to C has A A# B C). Going back to naming triads, C-E-G is a C Major triad and A-C-E is an A minor triad. A diminished triad is a triad that has 4 keys between both, the first pair of notes and the second pair of notes (eg B-D-F has B C C# D and then D D# E F).

So up to know we have scales (a collection of 7 notes starting on any note which we will call tonic), degrees of a scale (where in a scale a note or chord is), triads (chords formed picking three alternate notes on a scale) and chord quality (major, minor, diminished). Next step is notation.

As we said at the beginning, major and minor scales are families o

I may have the details wrong but I believe this is right: a woodwind player sees a note that is written as A on a normal stave, but when they play it, it comes out as a C. Or maybe I've got it the wrong way around and it comes out as F sharp? But essentially their scale is offset from the normal scale by a minor third?

How did this come about? How does this help? It would seem to make things very confusing, and mean that music was much harder to transcribe.

As a follow-up question: How did the British army model compare to the French and Prussian army models, and why did Chile not consider emulating the British model? How have the differences between the British, French, and Prussian army models affected the modern British, French, and German armies?

So I bought my first Tesla about 4 months ago, a new 2021 Model 3 Performance. It’s been absolutely incredible, fastest car I’ve ever owned or even been in. The Tesla technology in general has really grabbed me as well, I can’t stand driving anything else.

Im not in a rush to move on from this car, I have 7k miles on it so far and I could see putting on another 100k before I sold it. But, I love speed. I get jealous when I see Plaids or P100Ds on the road. And in general the model S would be a little better for my family, being a bigger vehicle.

A little searching looks like I could find a 20k - 30k mile 2018ish p100d for around $85k. I could make that work soon, though a brand new plaid of course is much more expensive and I’m probably a year or so out at least to being able to swing that.

Any advice would be great!
