## Factors of infection rate

I refer to J.H. Jones’ Notes on R0. Preliminaries The standard SIR model consists of a system of three differential equations ds/dt = -βsi di/dt = βsi – νi dr/dt = νi for the fractions s, i, r of susceptible, infected, and recovered (removed) individuals, dt = 1 day. β is the infection rate, i.e. […]

## Factors of infection rate

I refer to J.H. Jones’ Notes on R0. Preliminaries The standard SIR model consists of a system of three differential equations $$ds/dt = -\beta s i$$ $$di/dt = \beta s i – \nu i$$ $$dr/dt = \nu i$$ for the fractions $s, i, r$ of susceptible, infected, and recovered (removed) individuals, $dt$ = 1 day.

## Problems with shape files

I want to make a map with the coronavirus infected people by state in US . So the idea is to visualize a map with all states of US and see a range of infected people( i.e 500-2000 , etc) in all the map. This should be represented by different shades of one color. The […]

## SIR model without ode function

I have got following code of basic SIR model. I need the differential equation to be solved without ode() function or any other. Can you help me please how calculate this differential equations without using the ode() function? library(deSolve) library(shiny) ui <- fluidPage( titlePanel(“Choose amounts”), fluidRow(column(width = 4, sliderInput(inputId = “time_values”, label = “Days”, value […]

## How to properly print out a CSV file in python

I’m trying to scrape some data, write that data to a CSV file, then import that CSV file into R to do some analysis on it. This is more of a personal project to learn python and R, and I’m having some trouble printing to the CSV file. What I have now prints out in […]

## plotting multiple lines for SIR disease models

I want help on plotting multiple lines for different parameters say \beta for different values (\beta= 0.1, 0.2, 0.4 etc), the graph will be for dy_2/dt, meaning that plot(T, y_2( :,2) only, or plot(T,y_2(:,3)) then the plot to be Time vs Infected for different values of \beta. I have tried the following code: function EulerSIRTenga() […]
