It is now possible to collect a large amount of data about personal movement using activity monitoring devices such as a Fitbit, Nike Fuelband, or Jawbone Up. These type of devices are part of the “quantified self” movement – a group of enthusiasts who take measurements about themselves regularly to improve their health, to find patterns in their behavior, or because they are tech geeks. But these data remain under-utilized both because the raw data are hard to obtain and there is a lack of statistical methods and software for processing and interpreting the data. This assignment makes use of data from a personal activity monitoring device. This device collects data at 5 minute intervals through out the day. The data consists of two months of data from an anonymous individual collected during the months of October and November, 2012 and include the number of steps taken in 5 minute intervals each day

Kvalitet vazduha u Beogradu (Opstina Stari Grad) u periodu od 2010 do 2020. Crvena linija oznacava koncentraciju od 15 (petnaest) PM 2.5 cestica koja je od Svetske Zdravstene Organizacije (WHO) definisana kao dozoljena koncentracija tokom 24h i ne bi trebala preci tu vrednost vise od 3-4 dana u godini. Godisnja srednja vrednost PM 2.5 cestica inace ne bi trebala preci vrednost 5 (pet). Plava linija je regression line koja pokazuje trend tokom vremena. Sa dijagrama takodje vidimo da koncentracija PM 2.5 cestica neretko prelazi vrednosti od 100 pa cak i 200 tokom zimskih meseci. Dakle o kvalitetu vazduha koji udisemo prosudite sami. :(

The graph is showing the increase of the average temperature in Belgrade (Serbia) over 25 years (1995-2020) in each month of year. Why don't we have snow in December anymore? The increase of average temperature in December has gone from 1C in 1995 to almost 3.5C in 2020 (2.5C increase!) . All months are showing increasing trend with exception of May. A very steep increase is also observed in summer months with record gradient in August with increase of 3 degrees over 25 years! This could be attributed also to microclimate changes (e.g. increased number of cars and AC units). The bottom line, the increase in the temperature is real and we have been witnessing it in recent years through warmer winters and unbearable summers.

Number of actively infected people going back to 140k+ after daily numbers skyrocketed after Xmas holidays

Seem under control, at the moment. But it's expected to start growing again after they open everything on 3rd of Dec

Czech Republic is getting better

First time after 2 months a slight drop in number of active cases. It's scary to compare number of active cases 18 days ago which is now 3 times higher

There is over 70,000 tested active cases in Czech Republic as on 15th of October. This number has been doubling every two weeks over last month and a half. The number of hospitalized people and deaths have been following the same increase. The lock-down imposed yesterday should dampen the curve going forward but the next week will be probably the worst to come.

massive increase of active infections

The peak in March is not almost visible anymore. The new record 3000+ in one day

New record

Doubling number of (identified) infected people in only 10 days

Getting into exponential curve

The new record

Moving into new records since the beginning of the pandemic.

A different view I've made today - each point on the graph represent sum of infected people over previous two weeks. What does this tell us? Assuming COVID contagious period is around 14 days (roughly), this graph (again roughly) shows number of active (identified) COVID cases over time. In reality these figures are probably 2-5 times bigger but following the trend is a good indication in what direction is the pandemic going. This view is also revealing that the current situation is not only about few days with high numbers of infected but is starting to be worse than during peak of the pandemic back in April. I'm wondering why is the government delaying masks in indoor spaces?!

The new record!

CZ hit the top of the curve since March, the second worst day ever with 323 new cases. Time to start wearing masks again.

and we are back to the peak in April - 281 new cases yesterday

Jump over 200

S-Curve dampened. Good!

Note: version 2 - The dataset has been changed to V2 hence I had to rebuild the script to reflect the latest.

COVID-19 Czech Republic - Daily growth rate of confirmed cases for 02.07

S-Curve is becoming steeper, still 200+ cases today

The S-Curve has been dominating over last 7-10 days with the highest number since April mid. Mostly due to the clusters of infection. Keep distance, keep watching.

21.06.2020 - Hey -ho, we are swinging back. The increase day by day was the highest since April.
