Pacharapol Withayasakpunt started the topic What is greater London, as decribed in the study? in the forum Course Forums 3 years, 4 months ago
My understanding is greater London is like Thailand’s area around Bangkok (ปริมณฑล), that is, it doesn’t include City of London. However, greater London + city of London = London region, as one of the nine regions of England.
This center of the last image is white, because it is the real city of London.
In short, 32 boroughs are not city of London.

Thank you very much for sharing. It is always nice to see more code.
However, this makes it confusing with Local Moran’s I
– A positive value for Ii indicates that the unit is surrounded by units with similar values.
– The Getis-Ord Gi Statistic looks at neighbours within a defined proximity to identify where either high or low values cluster…[Read more] -
Pacharapol Withayasakpunt started the topic Exceedance probability vs Getis Ord Gi* in the forum Course Forums 3 years, 4 months ago
I understand Getis Ord Gi* as Hotspot analysis above baseline, but what are the differences from exceedance probability?
To add more the confusion, there seems to be multiple kinds of local spatial statistic G, as seen in R language help for
localG.G and Gstar local spatial statistics
Description
The local spatial statistic G is calculated… -

As far as I realized, minimum of
LondonSuicide.RDataandLDNSuicides.shpare required to learn this example.
However, as far as I have Googled, I failed to find this dataset online (in year 2021), as well as the associated documentations (what are the units of E, y, x1, x2; and what do the numbers mean?).

1. Why was the author interested in investigating the suicide problem in Thailand during the time?
– Within 2005 to 2014, the suicide rates in Thailand had been shockingly numbered at around 3,600 to 4,000 people every year. Also, the suicide rates had generally been rising since 2011, at more than 6 suicides per 100,000 inhabitants.

Railway can be CATEGORIZED to 3 kinds of values.
– RL_LTYPE (1)
– LENGTH (around 40)
– RAIL_ID (around 40)I think, I might be more natural to GRADUATE on LENGTH, but I am not so sure about the instruction to the assignment.

I would use both focus group discussion (FGD) using general participants; and in-depth interview to key informants; to develop deep understandings.
After that, a quantitative evaluation research might be helpful to improve the situation.

Usefulness is not enough. One should also consider “Ease-of-use”. That is, availability, approachability, environmental pressures, among factors.

If two confidence intervals overlap, the difference between two estimates or studies is not significant.
It still requires a statistics to compute difference between estimates, and still may produce a difference.
