49 new cases. New Singpost Cluster!

[Leongsam]

10th March -- 170 Singapore cases
19th March -- 340
27th March -- 730

Double every 9 days. Hence, exponential.

Doubling over a fixed period is not exponential. That is "2x". y=2x is a linear graph.

An exponential rise would be y = x squared.

Doubling over a 9 day period means that the curve follows the exponential equation

N = (N_0) * (2^(t/9))

where t = time measured in days, and N_0 is the initial population at the start of your accounting period.

I took a look at the raw data again and I've figured out what is changing because I have been tracking the daily rise and it is linear There is an imported cases component which requires a "+n" to the equation. I'll fire up my good old excel worksheet and see what sort of graph I come up with.

x^2 is not exponential growth!!

X^2 is polynomial growth!

My math is too rusty. I can't figure out how to plug clusters from imported cases into an equation. It has given me a headache so I'm going for a bike ride.

Because Singapore has not closed its borders the growth is not from single group of seeds. New seed cases are added and thus new clusters spring up. However because of the rapid contact tracing there is no exponential growth from each seed case.

In the old days I could have come up with an equation to forecast these numbers. However those days are long gone and I'm obviously past my use by date. Covid-19 could consume me and it would make no difference to the world anymore which is why I support the herd immunity approach in the first place.

If you could do it please post the math here. I would be forever grateful.

No need to argue here. John the Tan will verify your statement with smart lee.

Singapore is a trading nation. It relies on imports and exports to survive. Without imports the country is just a fishing village.

smart Lee said we are heavy into financial services -a bull shit activity that produces nothing ,just transferring money from A to B ; Smart Lee said
we depends very much on the tourism and service industry , import and export is not the major contributor of gdp.

The fact that there is a linear rather than an exponential growth in the number of cases shows that the PAP has this bug well under control.

Singapore is extremely lucky to have such a competent government in charge. If you compare the PAP gold standard vs the fiasco that is occurring in many other countries you should all count your blessings that the country can still function despite the fact that the world is in the midst of a pandemic.

KNN it does not really matter is linear or exponential KNN at a fix rate of eg 50 also means that everyone is waiting for their turn KNN exponential only means tio faster while linear is slower only KNN

Go virus go and fuck PAP.
