This is the kind of paternalistic, unscientific nonsense that #MECFS #Lyme #Fibromyalgia #HSD #POTS #MCAS #Pandas #Pans #EDS #VaccineInjured #FQtoxicity patients have endured for decades. Now it’s the turn of #LongCovid
I’m going to make an offer to our colleague. Hopefully @DrKGregorovic can convey this message as I am blocked. Happy to have a Zoom coffee with both of you. We can examine
-the paper @awgaffney has tweeted & discuss the flaws
-the evidence for biomedical causation in #MECFS & LC
-the evidence for the ‘false sickness beliefs’
-the quality of the studies advocating exercise & talking therapies
-studies looking at the outcome of exercise in #MECFS & #LongCovid populations
-cardiovascular & other outcomes in #LongCovid

I think that is fair? Let me know

What Is a Null Hypothesis?

A null hypothesis is a type of statistical hypothesis that proposes that no statistical significance exists in a set of given observations.

It has been an honour to walk alongside my friend & colleague of 21 years @BinitaKane & her daughter Jasmin on their courageous & inspiring journey. #LongCovid in adults children is real & serious. There are treatments available- sadly only for a fortunate few #TeamClots 1/n
(Everything I say is with the express permission of @BinitaKane). Jasmin is not the only child with #LongCovid who has been shown to have microclots & hyperactivated platelets. They are a consistent finding in kids & adults who have travelled for treatment to Germany & SA 2/n
Globally 100m are affected by this vile illness. In the U.K. alone this figure is estimated to be 1.8m, with 2/3rds reporting an adverse impact on their daily activities. 1% of primary & 2.7% of secondary school children fulfilled the criteria for #LongCovidKids 3/n

(PP ~ MUS) 🧵1/20
@doctorasadkhan @NurseDiane2020 @PandasPans @LongCovidKids @FiGullonScott @BASW_UK
This well-considered & positive document provides guidance to social workers (SW) to enable them to adopt professional curiosity & respond ethically to FII concerns. The following points are some that I feel are relevant to #PANS #PANDAS #LongCovid #MECFS #EDS communities 2/20
lt is recommended SW need to be aware of the lack of evidence for currently used indicators for FII & perplexing presentations and the high incidence of these indicators identifying children where illness is neither fabricated or induced #PANS #PANDAS #MECFS #EDS #LongCovid 3/20

[Data Analysis] 🧵
Exploratory data analysis is a fundamental step in any analysis work. You don't have to be a data scientist and be proficient at modeling to be a useful asset to your client if you can do great EDA.

Here's a template of a basic yet powerful EDA workflow👇
EDA is incredibly useful. Proper modeling CANNOT happen without it.

The truth:
Stakeholders NEED it far more than modeling.

EDA empowers the analyst with knowledge about the data, which then moderates the #machinelearning pipeline
While #pandas and #matplotlib are key to good EDA in #python, the real difference are the QUESTIONS you ask to your dataset.

As in all things, these tools are just tools. The real weapon is the analyst. You are in control, not the dataset.

I realized today one of the reasons I appreciate working for a system integrator. Last time this year I was training in #Scala and #Spark. Then, I was placed in a project using #python, #pandas, #pyspark and #sql. That ended 12/31/21 and I had a short break before joining...
a pilot project working with #terraform, #aws, #boto3 with #python, #informatica, #autosys and #shellScripting. Not to mention the increasing frequency of situations that are like "Here is some technology setup that you have never seen before, here is some rudimentary docs,...
Figure it out in 1 or 2 sprints, provide deliverable artifacts and documentation on the preexisting system AND the new artifacts. Thx, k. Bai!" Oh, and teammates you joined with, they all have a shit-ton of stuff, so don't expect replies to your msgs.

Cue: 1. panic, then...

Want a #Python #pandas data frame with all Apollo missions, indexed by date?

df = pd.read_html('https://t.co/1OfUmAGe6N')[2]

df['Date'] = pd.to_datetime(df['Date'].str.replace('(–.+)?,', '', regex=True))

df = df.set_index('Date')
The first line scrapes the Wikipedia page for the Apollo program, putting all HTML tables into data frames. The missions are in the third table, aka index 2.

The second line turns lines containing date ranges into single (launch) dates, also removing commas and hyphens.
That second line then takes the resulting cleaned-up date strings, and passes them to pd.to_datetime. The resulting datetime series is then assigned back to df['Date'].

Quick Thread : 5 Cool Advanced Pandas Techniques for Data Scientists

🧵👇🏻
#Python #DataScience #MachineLearning #DataScientist #Programming #Coding #100DaysofCode #hubofml #Pandas
1. Split data using pandas
In the code below, we are splitting the data into a random sample of rows and removing them from the original data after dropping index values.
2. Binning Data
Binning is a technique to group/bin your data into multiple buckets which is very helpful if you dealing with continuous numeric data. In pandas you can bin the data using functions cut and cut. First check the shape of your data i.e no of rows and columns.

Pandas is a fast, powerful, flexible and open source data analysis and manipulation tool.

A Mega thread 🧵covering 10 amazing Pandas hacks and how to efficiently use it(with Code Implementation)👇🏻
#Python #DataScientist #Programming #MachineLearning #100DaysofCode #DataScience
1/ Indexing data frames
Indexing means to selecting all/particular rows and columns of data from a DataFrame. In pandas it can be done using two constructs —
.loc() : location based
It has methods like scalar label, list of labels, slice object etc
.iloc() : Interger based
2/ Slicing data frames
In order to slice by labels you can use loc() attribute of the DataFrame.

Will Slovakia avoid „Czech scenario“?
Health minister #marekkrajčí 16.10. first time publicly compared the second wave COVID-19 trends in Slovakia and Czech republic in a chart showing that Slovakia is following the scenario in Czech republic with a delay of 2~3weeks.: Source: https://dennikn.sk/...
Trend chart from few days ago (22.10.) was even worse and clearly showing that Slovakia is repeating the Czech scenario: Image
Somewhere here we should be looking for motivation of the government in Slovakia and prime minister #igormatovič to solve the problem of rising second wave of epidemics and dark vision of collapsing health care by unusual way - #masstesting in combination with limited lockdown.

Pandyas of South India: #pandas #madurai #tamilnadu #pandyandynasty
The Pandya dynasty was one of the greatest South Indian kingdoms. But what made them so great?

The main reason for the greatness of Pandyas were their conquests. They almost conquered almost all of the South India and earned respect from all over.
Pandyan kings were smart enough to choose Madurai as their capital. Madurai had lots of rocks for buildings and was also rich in pearls. This allowed Pandya kingdom to trade all across the world.

Another way the Pandya empire gained power was through their architecture.

I used Matlab for image processing for years. Tried to switch to Python 10 years ago but too many tools were still missing. Tried again 5 years ago and haven't touched Matlab ever since! The combination scikit-image + @ProjectJupyter was a real game-changer! A few more things:
On top of the great classics scientific stack (#numpy, #scipy, #pandas, #matplotlib) there's an entire ecosystem of new tools to handle all sorts of complex problems. E.g. #napari to visualize and annotate multi-dimensional data. @dask_dev to handle very large images.
Complex ML tools for image denoising like content-aware image restoration #CARE (github.com/csbdeep/csbdeep) or point-scanning super-resolution #PSSR (github.com/BPHO-Salk/PSSR) which are documented as Jupyter notebooks that really work "out of the box".
