Visualization of Conflicts in Colombia and the World

-
The Uppsala Conflict Data Program (UCDP) has recorded ongoing violent conflicts since the 1970s. Using its dataset of 135 thousand records of organized violence globally since 1989, we can evaluate the distribution of conflicts in the world and in specific countries.
I listed here the top 10 countries:
Order Country Freq
1 Afghanistan 22,726
2 India 14,465
3 Iraq 6,488
4 Nepal 5,652
5 Pakistan 5,528
6 Turkey 4,826
7 Sri Lanka 4,576
8 Colombia 4,562
9 Algeria 4,098
10 Somalia 4,090

Since the year 2000, there are 98K records in the dataset. Again, the top 10 are:
Country Freq
1 Afghanistan 20,980
2 India 11,409
3 Iraq 6,109
4 Pakistan 5,335
5 Nepal 5,084
6 Somalia 3,664
7 Colombia 3,302
8 Russia  3,115
9 Nigeria 2,901
10 Sri Lanka 2,583

As we can see, the distribution of conflicts is highly skewed to the right since most countries are peaceful and conflicts are concentrated in certain areas of the world. In a recent working paper, we focus on the organized violence in Colombia. Applying a similar methodology to airport score, I count the number of conflicts within 50 km around each point on the map and create a measurement named conflict score.

Both Excel and R are slow in running this amount of data (500,000 records). Shall further investigate other options.

What does it mean "conflicts are highly skewed to the right"?

As I have revised, it means conflicts are highly long-tailed, some countries have very high values, while most countries have only a few or none conflict at all.

Power-law distribution (Pareto)& Zipf's Law: connection and how to fit the distribution of global city population

-

- This post counts for 3 days. - In short,  We use the histogram to outline the distribution, use rank-frequency plot (log-log plot) to identify the power-law distribution, and use maximum likelihood estimation to obtain the parameters. -  I will show 1 st , how the power-law function CDF and PDF can be derived from Zipf CDF; and 2 nd , this least square estimation by excel is wrong and how to get the right one. Historical background on the power-law distribution. - Power-law distribution is as common as normal distribution in the real world. In the 19 th century, Italian economist Pareto realized that 20% of the population owns 80% the wealth, which is the famous 80/20 rule. He later named the power-law distribution as Pareto distribution, which is what we studied in the probability course. - In the 20 th century, another main contributor, Zipf made a similar discovery in linguistics about the frequency of words used. - Besides social wealth, many things follow a hig

How to Draw Heatmap with Colorful Dendrogram

Heatmap with Dendrogram: Color Branches and Labels This data visualization example include: * Hierarchical clustering, dendrogram, and heat map based on normalized odds ratios * The dendrogram was built separately to give color to dendrogram’s branches/labels based on clusters using  dendextend * Heatmap is made by  heatmap.2  from  gplots  using the built dendrogram * The rows are sorted by means from highest to lowest, it can be done in either the dendrogram or the  heatmap.2 * Use color palettes from  colorspace Data YRBSS (Youth Risk Behavior Surveillance System) survey data from CDC. This example plots the odds ratios of 63 behavioral questions on one question regarding disordered eating. The odds ratios are median centered by column and log2 transformed Version 1: Color both the branches and labels library (curl) # read file from google drive library (gplots) # heatmap.2 library (dendextend) # make and color dendrogram library (colorspace) #

The Weighted Standard Deviation

I have revised the figures in the Conflicts in Colombia paper to add weighted s.e. Together with confidence intervals. Turns out to be not that complicated. Weighted s.d.: Add { geom_errorbar(aes(ymin=..., ymax=...), width = 0.2 } in ggplot2 to add the confidence interval into plots: The paper discussed how conflicts in Colombia makes cities develop more sluggish and denser. I will work more on it in the later posts. The complete R code for the figure # weighted means for global 200 sample ggplot(data=m4_mean_g_g200, aes(x=year, y=wm, group=Group, color=Group, shape=Group))+ geom_point(size= 4 )+ geom_line(size= 1 )+ geom_errorbar(aes(ymin=CI_low, ymax=CI_high), width= .2 )+ ggtitle( "Urban Density Change Over Time in 200 Cities" ) + labs(x= "Year" , y= "Average City Density" , color = "" , shape= "" ) + scale_y_continuous(limits = c( 30 , 150 ))
