Do you know anyone who has cruised on the Coral Princess?

We are doing a cruise at the end of this month on the Coral Princess. We are interested in feedback from anyone who has cruised on this ship (or any other Princess ships). We were reluctant to do another Princess cruise after our experiences last year when we were charged USD $ 376 (NZ$600) for…

COVID-19~ 2020 outbreak~ Conclusions up to August 6 2020

We draw conclusions from our previous posts based on cases up to August 6 2020. We have already looked at worldwide estimates for Ro if Ro ~ exp(2.5r – 2.5), Ro ~ exp(sr – s), and Ro ~ exp(tr – t) where Ro is the average number of people that one person with COVID-19 may…

COVID-19~ Should a weighted average be used to estimate r*?

We have used two ways to calculate r*, an estimate for r. We currently use the first (“Old”) method to estimate Ro for the early 2020 outbreak. The only difference is on the second line where the average is used in the top calculation  a weighted average is used in the bottom calculation. Note that…

COVID-19~ Worldwide values for Ro in early 2020

We look at values for Ro worldwide in 2020 where Ro is the number of other people a person with COVID-19 may infect on average over a 10-day infectious period. We have looked at this post: COVID-19~ Better values for Ro We obtain this list: This PDF contains more countries: COVIDWorldwidet Shared Posts (Pingbacks)

COVID-19~ Better values for Ro

In this post we obtain better estimates for Ro by increasing our minimal estimates for Ro. We have already looked at minimal values for Ro based on our previous results and simulations: COVID-19~ Minimal values for Ro In the above post we looked at EXP(sr-s). We consider t = s*1.05 and look at EXP(tr-t). i.e….

COVID-19~ Minimal values for Ro

In this post we look at minimal values for Ro based on our previous results and simulations. We have already looked at worldwide estimates for Ro if Ro ~ exp(2.5r – 2.5), where r is a daily increase in case numbers early in an outbreak. Ro is the average number of people one person may…

COVID-19~ Is 9.75(r-1)^2+1 a good estimate for Ro?

In this post we consider if Ro = 9.75(r-1)^2+1 a good estimate for Ro. We have already looked at worldwide estimates for Ro if Ro ~ exp(2.5r – 2.5), where r is a daily increase in case numbers early in an outbreak. Ro is the average number of people one person may infect when there…

COVID-19 in 2020~ Extending using approximating polynomials for Ro

We extend our range for estimating Ro using another polynomial. We have already investigated if r^3 (r cubed) is a good estimate for Ro for COVID-19: COVID-19~ World-wide estimates. Is r^3 a good estimate for Ro? We have already looked at worldwide estimates for Ro if Ro ~ exp(2.5r – 2.5), where r is a…

COVID-19~ World-wide estimates. Is r^3 a good estimate for Ro?

We investigate if r^3 (r cubed) is a good estimate for Ro for COVID-19. We have already looked at worldwide estimates for Ro if Ro ~ exp(2.5r – 2.5), where r is a daily increase in case numbers early in an outbreak. Ro is the average number of people one person may infect when there…

COVID-19~ Worldwide estimates if Ro ~ exp(2.5r – 2.5)

We look at worldwide estimates for Ro if Ro ~ exp(2.5r – 2.5), where r is a daily increase in case numbers early in an outbreak. Ro is the average number of people one person may infect when there is no immunity in the community over a ten-day infectious period, and “exp” means “e to…

COVID-19~ Does Ro = exp(2.5r – 2.5)?

In this post we consider whether Ro = exp(2.5r – 2.5) is a good estimate for Ro where r is the daily increase in case numbers early in an outbreak. We consider this graph: We have already considered r^2.5 and r^(10/3) for various values of r. We add these to the graph: Below are the…

COVID-19~ refining our estimate for Ro

We have considered that Ro = 1.1r^2.5 provides a good estimate for Ro, where r is a daily increase in case numbers early in an outbreak, and Ro is the average number of people that one person may infect when there is no immunity over a ten-day infectious period. We now consider if Ro =…

COVID-19 in 2020~ 1.1r^2.5 compared with literature meta-analyses

In this post we update our earlier results and compare our results with meta-analysis in the literature. In 2020 we developed a formula for Ro, the number of people one person may infect over a ten-day period when there is no immunity, based on the daily increase, r, in the number of cases of COVID-19….

COVID-19~Worldwide estimates for Ro in 2020

We se the results in our previous post to calculate worldwide estimates for Ro in 2020 using data up to mid-August 2020. We obtain the following table: For more countries see: COVIDWorldAllCasesCPMNZcorr Notes: The date and number of cases are when r* was calculated. The estimate for Ro is the value in penultimate (second to…

Covid-19~ Does 1.1r^2.5 provide a good estimate for Ro?

We consider whether  for COVID-19, 1.1r^2.5 provides a good estimate for Ro,  the number of people one person may infect when there is no natural immunity. We have already established that r^2.5 provides a good estimate for the effective reproduction rate Re, where r is the daily increase in case numbers. We want to estimate…

Analysis of Polls: What are the fairest tax rates for New Zealand overall?

We will analyse the results of three Polls on Neighbourly, a New Zealand social media suburb-based site. The Polls were viewable by almost 25,000 residents (24,475) in suburbs surrounding my own in Titirangi in west Auckland. Very few people chose to respond. You can view the responses here: https://www.neighbourly.co.nz/message/view/70275327 https://www.neighbourly.co.nz/message/view/70273456 https://www.neighbourly.co.nz/message/view/70269533 You can view my…

Part 2: What are the fairest tax rates for New Zealand overall?

We again consider the best tax rates for New Zealand. We again consider the current tax rates: We eliminate the lowest two ideas from our last post: What are the fairest tax rates for New Zealand overall? We look at zero tax for the first $5,600 of income then: 17.5% tax under $70,000 28% tax…

What are the fairest tax rates for New Zealand overall?

New Zealand has a general election underway this year. Parties have different ideas about what the tax rates should be. We will ignore subsidies in this post. We will only consider the tax rates themselves.

A range for Ro for COVID-19 early in 2020

In 2020 we developed a formula for Ro, the number of people one person may infect over a ten-day period when there is no immunity, based on the daily increase, r, in the number of cases of COVID-19. This year we considered that Ro = r^2.5 gave a better estimate for Ro. We obtain and…

Matches in two decks of shuffled cards: My hands should be sore!

When reading the library book by Adam Spencer below, a question was asked #52- can you guess why? My hands should be sore from shuffling two decks of cards 2,000,000 times, each time going through the two decks turning over one card from each deck to see how many times there was a match (same…

NZ COVID-19 Polls

We look at two recent New Zealand COVID-19 polls. Both polls were posted on Neighbourly, a New Zealand suburb-based social media website. The first poll is ongoing nation-wide. The second poll is based around some suburbs in West Auckland. For all my COVID-19 posts see: https://aaamazingphoenix.wordpress.com/tag/coronavirus/ The following (interim) results occurred: With one more vote…

COVID-19 Worldwide in 2020~ GIGO: New Zealand has moved up one position!

A duplication in our source data we obtained from an outside source has meant New Zealand has moved up one position in world rankings. GIGO means Garbage In Garbage Out. The new rankings are: Norway and New Zealand have changed positions. The last column ranks countries by r* our two-day average estimation for r. We…

COVID-19 Worldwide in 2020~ Computation of r and Re in Excel

In 2020 we looked at Case numbers of COVID-19 worldwide using data up to 6 August 2020. Data by country/region daily was in 28,800 rows in an Excel 2010 spreadsheet. We used initially this methodology to estimate daily increases, r, over five-day intervals: C and r are the case numbers and value for r (daily…

The rise in case numbers for infectious diseases

In this post we look at the potential rise in case numbers for major infectious diseases. In our last post we considered Ro = r^2.5 where Ro is the number of people one person may infect when there is no immunity and r is the rise in case numbers over a short period near the…
