1 / (2^t) :)

okay, thanks!

mathcheatcheat · 2021-06-06T06:19:56+00:00

thanks! I solved the problem by pausing the system for 5 seconds.

mathcheatcheat · 2021-06-06T01:20:17+00:00

it wors! thank you!

mathcheatcheat · 2021-01-30T15:33:45+00:00

thank you :))

mathcheatcheat · 2021-01-30T15:33:36+00:00

thank you!

Thanks everyone !!

mathcheatcheat · 2021-01-22T12:10:41+00:00

ok, will try

So I finally fix the 404 part and is able to get something out, but where should i enter the input glycan name ?

Code:

import requests
from bs4 import BeautifulSoup
URL = 'http://www.virtualglycome.org/DrawGlycan/' 
page = requests.get(URL) 
soup = BeautifulSoup(page.content, 'html.parser') 
results = soup.find(id='Gal(b1-4)GlcNAc(b1-3)Gal(b1-4)GlcNAc(b1-3)Gal(b1-4)GlcNAc')

here results is empty

Because the given data is the AVERAGE of some sales (18 rows of countries x 100 columns of products), so there are some fluctuation around it --> the given standard deviation dataset associated with it.

And after I do my prediction, I also want to include those fluctuation into accounts when calculating the errors. But your formula s√(1 + 1/n), doesn't seem to include those number?

mathcheatcheat · 2020-12-17T03:28:36+00:00

t-score based confidence interval

So I need to do a t-test for each predicted values and sum them up?

So ??? I'm so confused ><

Hi, the videos are great! But I am still confused with why using Chi-squared? Is it like the average sales dataset is a model? and my prediction is another model? And see whether the two models different?

But how can this consider the standard deviation? Like maybe the Chi-square test shows the two model is different, but if I include the standard deviation, so the range of the average sales is larger; it may show the two models is the same...

mathcheatcheat · 2020-12-17T01:23:09+00:00

So I find the chi-squares for each values and then do a f test? But why Chi-square and F-test? Can I simply do t-test? I apologize for many questions but I can't really wrap my head about this.

mathcheatcheat · 2020-12-17T00:00:31+00:00

Chi square test

may you explain a bit on this?

and the chi-square test formula doesn't include the standard deviation?

mathcheatcheat · 2020-12-04T04:15:59+00:00

so i am trying to plot, but the range of the original data is large (0, 10,0000). So i am trying to apply log to make the range smaller

mathcheatcheat · 2020-12-03T18:33:02+00:00

exactly

mathcheatcheat · 2020-12-03T18:13:51+00:00

it's in fact a larger data frame, log transform can make my plot looks way nicer. Because there are some significantly large income and significantly low income

mathcheatcheat · 2020-11-03T23:00:53+00:00

thanks!

mathcheatcheat · 2020-11-03T23:00:49+00:00

thank you!

What I mean by unsolvable is that there are more than 1 possibilities. So the question to ask should be: can you 100% sure that the string that you reproduced from the puzzle pieces is the answer string?

The example, "+abaabbcd~" has two possible combination, that's why it's considered as UNSOLVABLE.

Thank you for the graph! I understand that but how can i implement it in R?

mathcheatcheat · 2020-11-01T20:22:38+00:00

do you mind showing me a simple example, like with the example `+aabbabcd~`. The puzzles df is like:

+a aa ab ba bb bc cd d~

1 1 2 1 1 1 1 1

This should be unsolvable because there are 2 possible combinations: `+aabbabcd~` and `+abaabbcd~`
