Upon looking at the text content for the Cleveland CSV file, I cannot really find missing data (supposedly ,, two-commas together), so I am confused as well to what is wrong.

PAM method, rather than kmeans can still run, though.

But then, how many clusters do I really need? I asked in another post.

This graph, actually.

Would be nice if I can add hovering dialog box (to tell which point) as well.

Since we are using complete linkage clustering, the distance between “35” and every other item is the maximum of the distance between this item and 3 and this item and 5.

From the link, at the top of PDF can be found — Defining Cluster Distance: The Linkage Function

Complete linkage, which is more popular, takes the maximum distance.

Most updated lab results and vital signs seem to have no substitute, therefore should be easy and best to implement first.

OCR using image technology might be good, if it is accurate. Forget handwriting, it has to be prove-read first. Older printings and PDF might be worth OCR’d — but it is still better to just upload the doc files…

1. There is a lot studies about creating a PHR prototype, why so few of them are implemented?

Whenever there needs to be a collaboration multiple parties (between hospitals, and between caregivers and general public), it is less likely to be implemented.

For example, PHR with hapi-fhir wouldn’t work without an HL7-compliant system, e.g. OpenEMS.…[Read more]

For MacOS, you also need ‘shiny’.

So, install ‘sp’, ‘foreach’, ‘shiny’ first, then try install ‘INLA’.

Discussion 1
According to this paper, the preventive measure achievement rate is around 50-70% of patients. The implementation of CDS did not improve the rate of preventive measures as much as we think when we use the same calculation. If you were a CDS developer, which features or options you want to add on in order to improve the performance of…[Read more]

Good electronic system come with price , how do we develop it in low resource country like Myanmar?

I think we have to separate things.

Infrastructures, such as fast Internet are expensive, and have no other to replace. A solution is to work offline-first, and sync only when you have Internet connection, such as EpiCollect5. Web…[Read more]

It is hard to guess, but I would consider the following factors,

Please see my COVID19 Dashboard.

I feel PowerBI a little slow and lagging for my wanting to make decisions…

Map is nice, but if we try to make it a flat projection for the whole world, it is distorted.

Funnel chart is just akin to Bar chart.

Tree map is a very good idea to compare numbers.

Scatter chart is a good idea to show relationship between 3-4 variables, but I personally think time series animation is too complicated and not always understood…[Read more]

– Sparkline is used to show general trend of Confirmed case over time.
– Line chart with forecast is used to show future trend, with confidence interval.
– Clustered bar chart makes it easy to compare between categories.
– Donut chart and sunburst makes a nice comparison over 100%.
