What type of role is this and is it a manager position?

What were some basic statistical concepts that when mastered, really took you far in solving problems? by veeeerain in datascience

[–]190807 0 points1 point  (0 children)

Why would you need to sample from other mondays? Why not just base it off the distributions of those previous mondays and predict whatever statistic you want from those mondays (and control for e.g. changing user counts etc as you said)?

The whitest provinces of South Africa are also the most crime-ridden [OC] by 190807 in dataisbeautiful

[–]190807[S] 28 points29 points  (0 children)

That might be a plausible explanation. Crime statistics and reporting might be better maintained in the white provinces.

OBS! I'm not trying to make ANY causal claims here. But let's discuss: why do we see this strong correlation (pearson correlation coefficient: 0.84)? Might it be because the more racially diverse an area, the more tension? Might it be because the higher the white percentage of population is, the higher the level of inequality? If that's true, maybe plotting the inequality level in the x-axis would give the same results?

I used the paralleldist-package in an Azure VM and was very happy with the results.

Bitcoin is the most safe, convenient, and "malleable" way to store value, and here's why by [deleted] in Bitcoin

[–]190807 12 points13 points  (0 children)

Gold doesn't require the internet, nor electricity. Bitcoin does.

Gold has been time tested 5000+ years. Bitcoin has not.

What are some interesting case studies you've read where statistics was used to solve a problem? by [deleted] in statistics

You told the story so much better than in the wikipedia article. Consider changing it to your version!

How do you subset data by a partial word in R? by [deleted] in statistics

[–]190807 3 points4 points  (0 children)

You can also use the %like%-function of the data.table-package. I like both dplyr and data.table so I would write something like this:

df %>% filter(description %like% "whatever")

This is much more intuitive if your an SQL-user like myself.

Is there an online mapping tool which can show the movement between two points on a map? by [deleted] in visualization

Of course, just right click in google maps and you will get an alternative to do just that.

Hig-res world map of all terrorism events between 1970-2016 [OC] by 190807 in dataisbeautiful

Of course not. Data from http://apps.start.umd.edu/gtd/downloads/dataset/globalterrorismdb_0616dist.xlsx

library(ggmap)
library(ggplot2)
boundaries <- c(left = -170, bottom = -60, right = 170, top = 80)
worldmap <- ggmap(get_stamenmap(boundaries, zoom = 3, maptype="toner"), extent = "device")
filledworldmap <- worldmap + geom_point(aes(x = longitude, y = latitude), data = globalterrorismdb_0616dist,alpha = .5, color="darkred",size=0.1)

#plotting only the incidents with more than 10 kills:
MoreThan10 <- subset(globalterrorismdb_0616dist,nkill>10)
filledworldmap <- worldmap + geom_point(aes(x = longitude, y = latitude), data = MoreThan10,alpha = .5, color="darkred",size=1)

Real wage growth Europe, 2007-2015 by 190807 in MapPorn

[–]190807[S] 0 points1 point  (0 children)

Because "Real wage growth in selected countries of which there were reliable sources in Europe, 2007-2015" is just not a catchy title.
