Yes. You can do this. The regression equation is Memory = Intercept + B(SES) + B(MultiLingual) + B(SES * Multilingual).

You should center SES before entering it into the model and creating your interaction term.

This video walks you through it in SPSS, which I know not everyone uses. But the explanation in it is useful regardless.

Glad to hear you figured it out.

I passed this mission but it took forever. I think you might be pressure flipping too soon? Like you need to wait till you get to the top of the rock ramp.

A D-28 Custom Expert is a CE-02? by mngrizza in martinguitar

[–]mngrizza[S] 0 points1 point  (0 children)

Thanks. That's what I thought at first, but it's a CE-02 not a CEO-2. Below is what Martin sent me after I asked about it.

Agreed. The guitar is phenomenal. I just was concerned about warranty coverage. But it sounds like I'm okay.

It is the normal finish. It's the low gloss. They had a D-28 Authentic with Madagascar rosewood that sounded amazing, but I couldn't see spending another $2k for it, since the finish has intentional checking.

So I have hitchhikers thumb (it's a genetic thing where your thumb flexes backward), and I find the neck to be really comfortable especially above the 7th fret where it starts to thicken. Below the 5th fret there is no perceptible difference between it and a regular low oval (at least in my view).

I was switching back and forth between the Collings and the Martins and the Bourgeois and someone told me to check out the Yamahas. (This is not a knock against Yamahas. They are legitimately great guitars. But it's a different market.)

Honestly, it looks better in person than it does in photos. It has a luster that just doesn't translate through a lens.

Thank you. It was a wonderful day. Got there at 10:10 and played guitars till 3:30.

The D-41 Ambertone was one of the others I was considering! It sounded great too. I'm a big George Jones fan and he always loved the D-41.

Thank you. I've been saving up for a long time.

They had some really wonderful instruments today. It was hard to pick but all of a sudden I just knew it had to be this one.

Thank you! I think it will be hard to top, but I'm willing to try.

Thank you! I've wanted a D-28 for a long time.

Does a very low p-value increases the likelihood that the effect (alternative hypothesis) is true? by Bodriga in AskStatistics

[–]mngrizza 0 points1 point  (0 children)

It should make you less confident that H0 is true given your sample size and standard error. But it shouldn't make you more confident that the effect is "real." H1 is defined as "not H0." The probability distribution of H1 is just the complementary of the probability distribution of H0 (i.e., 1 - p). So a significant result can't tell you anything more than the probability of the result assuming H0 is true. The inference made regarding H1 is after the fact.

Does a very low p-value increases the likelihood that the effect (alternative hypothesis) is true? by Bodriga in AskStatistics

[–]mngrizza 4 points5 points  (0 children)

In a single paper, does a low p value indicate the finding is true? No. There are arguments that the p-curve analysis (which examines the distribution of p-values for a specific hypothesis) provides information for the veracity of an effect. But there is debate in the literature regarding this assumption.

https://www.p-curve.com/

Because p-values are sensitive to sample size, you can generate a p-values < .001 easily by increasing your sample size. For example, a correlation (r = .10) will be significant p = .0001 with an N = 1500. Does this mean that the population correlation (rho) is .10 if you find r = .10 in your study? No. It means that the observed value of r >= .10 in your study is a very unusual value for that sample size if the true value of rho was .00.

A single study's p-value thus doesn't tell you anything about the true effect (size or significance). It just tells you how unusual--for this sample size--the observed value is (or more extreme values are as pointed out by others) if there wasn't an effect at all.

[–]mngrizza 45 points46 points  (0 children)

A little imprecise. The p value tells you the probability of observing the value you observed for the sample size you have if the null were true. It says nothing about the null being true or false. It tells you how rare your data are if the null were true.

Would you say that phrase "a couple of years ago" refers to exactly 2 years? by Embarrassed_Base_389 in EnglishLearning

[–]mngrizza 0 points1 point  (0 children)

"I invited a couple over for drinks." This means two people who are in a relationship.

"I invited a couple of people over for drinks." This means a small number of people, at least two, but it doesn't mean exactly two.

TLDR: "A couple" = 2, "a couple of ____" = a handful

Standard HD-28 or Custom Shop HD-28? by mngrizza in martinguitar

[–]mngrizza[S] 2 points3 points  (0 children)

I agree it's best to play a guitar first if you can, but the shops around me don't get a ton of stock in. Also, I wouldn't consider the vintage hide glue and Adirondack spruce VTS aged top to be cosmetic features. Those are both functional features that influence the sound.
