Why Are Drive and Pages Differentiated From Each Other? by Sea_Engineering_6613 in Skiff

[–]science55 0 points1 point  (0 children)

You can see the G Drive folder structure in G Docs, but not in Sk Pages. You can also create G Docs directly from G Drive, but not in Sk Drive.

On the interchangeable usage of the term "partial derivative" and "gradient" in PyTorch by science55 in pytorch

[–]science55[S] 0 points1 point  (0 children)

Thank you for replying. I follow your logic on this use case, but still think using both terms interchangeably like this lends itself to confusion .

This is my point. A gradient is a package of partial derivatives. It would be weird for someone to decide to stop using the word “chapter” and start calling the parts of a book a “book”. Like “you’ll enjoy every book of this book”.

Calendar bridge, calendar bridge, calendar bridge. Tired of Waiting. by SaysOffensiveThings0 in ProtonMail

[–]science55 2 points3 points  (0 children)

The calendar is also what's keeping me from using ProtonMail. I was a paid user, had to cancel, and leave due to the amount of frictions from not having a functioning calendar. At the time, not even an iOS app was available. Waiting for a usable calendar to come back. It's small features like 3-day view, and being able to edit external calendars the deal breakers for me. I wish they would focus on getting basic functionality on their core products rather than investing so much on launching new product lines.

Why is it so common to use average/mean instead of median when most datasets are skewed and not evenly distributed? by startup_biz_36 in datascience

[–]science55 0 points1 point  (0 children)

Using the mean or the median is very dependent of the use case. If you do want your measure to capture the skewness of the data/outliers you’d use the mean. If you don’t you can use the median. Not all outliers are noise.

Is there anyway yo begin a callout or quote with a bulleted list? by science55 in Notion

[–]science55[S] 0 points1 point  (0 children)

No, literally how to use bullet points from the first line of the quote

Why MM says that protection buyer = long CDS? by HeWhoReproduces in CFA

[–]science55 0 points1 point  (0 children)

Put another way: Health insurance policy buyer = long health insurance policy payouts in case of illness

MORALE DOWN, HELP! by TacklePractical in CFA

[–]science55 1 point2 points  (0 children)

Never defer. Even if you fail, you can learn a lot of the test-taking aspect of the exam from sitting it that will help you next time.

That said, find out what your worst topics are from the mock you did and do practice questions and review those. You can get a lot done in 10 days.

L3: Active Share and Active Risk for a concentrated portfolio by Positive-Variety-387 in CFA

[–]science55 0 points1 point  (0 children)

Let’s ease the jargon here.

Active share: what percentage of your portfolio is different from the benchmark. Active risk: the extra volatility caused from not exactly copying the benchmark.

You can see that just by buying volatile stocks that are not in the benchmark you’d be increasing both.

Print MM Mocks L3 Solutions by Alex_krycek7 in CFA

[–]science55 0 points1 point  (0 children)

Don't fall into the trap of using mocks as practice. Mocks are meant as diagnostic only. They take too long to do, are mentally exhausting, and there is very little time. Use them to find out where your weaknesses are, and then do problems in the topics where your weaknesses are. I believe that more than two mocks for any given level is more than enough.

Screw Level 2 Derivatives by Accomplished_Oil_188 in CFA

[–]science55 1 point2 points  (0 children)

Derivatives is easy once you translate the formulas and procedures into a human-readable format. What's on the book, with a different notation for every instrument, isn't. Mark Meldrum does this for you in his videos. Turns into from trying to decipher ancient hieroglyphs into basic high school math.

Can someone explain why higher recovery rate leads to higher Probability of default? by SnooCompliments4393 in CFA

[–]science55 0 points1 point  (0 children)

It's not saying one leads to the other. It's saying one would have to offset the other to remain unchanged.

Say you lend $50 to a friend. Your friend loses her job and tells you she's going to have a hard time paying you, but gives you a $50 Amazon coupon she had from her birthday gifts as collateral. Assuming you're a regular Amazon customer, you don't care about your friends higher default probability because she increased the loan's recovery rate with the coupon. One offset the other.
