Has the curve flattened? During the Coronavirus pandemic. statistics such as number of new daily cases are gathered to help study the growth or decline of the spread of the virus. A country's cumulative new case data after 100 cases is provided for this problem. The data is taken from htips Jinformationisbeautiful net/datay and shows accumulative data for 128 days. The data plot is shown in the figure below. One important statistical parameler is the maximum value. Finding the maximum value and the relative location of the maximum in data, like the date of the occuracne of the maximum number of cases, can help in turther studias of the progression or digression of the disease From the above. data can be modeled with an exponential function in the form of Y(x)=C′(1−exp(−X/D)), where C and D are constant. parameters of the model. Howeyer an exponential model can be hard to work with. An exponential model can be linearzed using the Tayior cxpansion. In other words:
Write a program that finds the linearization parameters for this data set. Between orders 2 to 5 , which potynomial order is the best fit for the data? The dataset is accumultive data, so no negative data points exist. However, some polynomial models may have some negative data points due to modeling error. The nonphysical data points dony havo any significant effect in the modeling for the purpose of this problem. The best polynomial fit order can be decided visually by plotting the original data and the linearized model, and doing a visual compariscn. Given: - accumNumi a 1D array containing accumulative number of cases for 128 days: The output is: - polyNomOrder: the order of polynomial best fitting data: - polyNomCoeff: the coefficients of the polynomial equation. Festrictions: polyfite) cannot be used tor this problem, as this system is an overdetermined system of linear equations, The polynomial coefficients should be found solving the system of linear euqations.
