3. Introduction
▪ Country/Regional Data and Plots
▪ USA State Data and Plots
▪ USA Models
▪ USA Red vs Blue
▪ Stay @ Home
▪ Barber Shop Index
▪ Questions
▪ Interesting Metrics from Data
6. Deaths by Country
Deaths per 100k of Population
EU in Yellow & US in Blue
As this trend on Y2 Axis goes to zero the
cumm curve above is flattening (no more
deaths)
13. Barber Shop Index
Many of the States are in various
“phases” of opening AND those
phases are not the same… Thus
the Barber Shop Index.
Tell me again why Barber
Shops are closed in Hawaii
& Oregon?
14. Mortality Rate (MR) and the Flu
▪ Mortality Rate is defined as:
▪ Number of Deaths per 100,000 people
▪ A Mortality Rate of 10 in the US population of 330MM people corresponds to
33,000 deaths
▪ Note the historical plot of the MR of influenza from 1930 to 2004.
▪ Link to article in the references; it’s a good read
▪ I found this conclusion relevant:
▪ The considerable similarity in mortality seen in pandemic and non-pandemic influenza
seasons challenges common beliefs about the severity of pandemic influenza. The
historical decline in influenza-classed mortality rates suggests that public health and
ecological factors may play a role in influenza mortality risk. Nevertheless, the actual
number of influenza-attributable deaths remains in doubt.
▪ I utilized the estimated 2019 population of various regions (i.e. New
York, USA, Michigan, etc) and deaths attributed to COVID-19 in those
regions to compare the variance in mortality rates across various
regions of the country
▪ By using Mortality Rate, it normalizes the data to aid in better regional
comparisons
▪ Why normalize it?
▪ Different regions or states have different public policy, population density, etc that are
impacting their states’ mortality rates for COVID19
See References #4
15. How to read Statistical Model
▪ The top plot is cumulative COVID-related deaths
over time
▪ Attempts to estimate the total deaths from COVID19
▪ This model is better for showing the efficacy of the
best fit model
▪ It also shows how the impact of changes in behavior
can impact total deaths.
▪ Note, New York early on had an MR tracking close
to 100, which subsequently made a step-change to
~70
▪ The bottom plot is daily death rate over time
▪ This plot better shows the peak death rate as well as
when to expect improvement
▪ The models utilize mortality rate as the variable
▪ Curve fit model, estimating mortality rate based on fit
to actual data and start times for the region
▪ Mortality Rates of Low, middle and high are used to
bracket actual data to show changes in trends
Reference #3 is the white paper for the numerical model used to generate all the models
16. The Model
▪ The model is a simple statistical cumulative numerical method, from
which both cumm and daily plots are made
▪ I started with the theory that the virus, based on info at the time, was a
60 day cycle, we are now at 88 days
▪ I curve fit the model to the actual data by changing MR and Start Date
▪ I added the ability to change the period because the data was clearly pointing to a
longer cycle than 60 days.
▪ Started with 60, then 74 and now 88 days
▪ The curve fit is thrown off by the additions of past deaths as the CDC changes the
guidelines as what is a COVID19 death
20. New York Actual vs Models
Daily Plot
Why is there a big spike?
As reported by many news agencies and the
President, the states are going back and
reporting to the CDC “probable” deaths of the
China Virus. The daily deaths after April 15th
includes both current deaths + probable
deaths.
34. Red vs Blue Deaths (2016 Presidential Election)
Red is Republican and Blue is Democrat
Added “Daily Deaths” on right y-axis to show how fast the curve is flattening (zero deaths)
35. Red vs Blue… Why
▪ The Trump Administration (and likely the Constitution) left many decisions to
the States, including decisions to shut down commerce
▪ States like CA shut their whole state down at once; other states, like Texas, left
it up to the cities and counties
▪ This brings up an interesting political dynamic that could impact different
regions at different rates
▪ There has been some interesting information coming out around
Hydroxychloroquine treatments, but some state bureaucracies have either
held up the use of the medicine or limited its use
▪ Mortality Rate is affected by several variables including public policy and
population density
36. Questions I am trying to answer
▪ Is this world coming to an end? (No)
▪ How does this compare to the flu?
▪ When will this end?
▪ What is the effect of different public policies?
▪ Can other states, regions, countries learn from the variability in public
policy in the US?
▪ How bad could it have been without stay-at-home policies?
▪ Is social distancing enough?
▪ Do we have to shut the economy down next time?
37. Interesting thoughts on the Data
▪ NY has a more than ten times higher mortality rate than the rest of the US
▪ With a Mortality rate of 100 in NY:
▪ What caused it to be so high?
▪ What causes the variability in the Mortality rate trends?
▪ Is public policy to blame for both failure and success?
▪ Trump Admin estimated 100k to 250k deaths in the US, this model is currently estimating 100k deaths in the US
▪ Where did they get 100k to 250k? Overestimating early trends in NY and applying it to the entire US?
▪ Why are we seeing the trends change upwards after what appeared to be a peak?
▪ This appears to be a change in policy of submitting probable deaths to the CDC for past cases starting April 15th. I have updated all the models capture the
increase MR.
▪ Red States have ~23% of active COVID19 Cases, but ~16% of deaths
▪ Population Density has an impact here but possibly one or more of the following do too:
▪ Public Policy
▪ Population behavioral trends
▪ homeless population
▪ Avg age of population
▪ And many more that I probably don’t understand
▪ Re-Opening of the States in many cases has been far more political than it has been scientific
▪ Every state has small differences in the “Phases” of opening, that is why I have the Barber Shop Index.
▪ For instance California has technically expired the S@H order HOWEVER even the New York Times calls them only regionally open
