# Forecasting total deaths from Covonavirus

Almost 60, 000 people have died of Coronavirus and we have not reached even the peak of expected distribution of deaths. Expected distribution is somewhat bell shaped curve. Like plot of China's death because of Coronavirus-

Here I have taken machine-learning based approach to forecast total deaths from corona virus.

python( 3.6) code to do analysis-

Step 1 - loading required dataset( John Hopkins dataset from Github)

* def load_data():*

* **import** pandas **as** pd*
* url**=**'https://raw.githubusercontent.com/CSSEGISandData/COVID- 19/master/csse_covid_19_data/csse_covid_19_time_series/time_series_covid19_deaths_global.csv'*
* corona_data **=** pd**.**read_csv**(**url**,** sep**=**','**)** *
* corona_data**.**head**(**)*
* **return**(**corona_data**)*

data is updated daily, so one will get till date information of cases.

Step 2 data preprocessing- visit github page-

Step 3 forecasting deaths-

```
multiplicative ets model-
```*fit2_mul **=** **ExponentialSmoothing**(**plot_dealts1**,** seasonal_periods**=**None**,** trend**=**'mul'**,** seasonal**=**None**)**.**fit**(**use_boxcox**=**True**)*
additive ets model -
*fit2_add **=** **ExponentialSmoothing**(**plot_dealts1**,** seasonal_periods**=**None**,** trend**=**'add'**,** seasonal**=**None**)**.**fit**(**use_boxcox**=**True**)*

Step 4- As this is not exact time series analysis. As actual distribution of deaths is bell shaped curve. We need to assume that peak will come in x number of days. Then we calculate number of deaths till peak and just multiply it with 2, to get total deaths.

the above plot is expected number of people dies if corona virus takes 15 more days to reach its peak.( additive etc model)

total deaths with additive etc model assuming it will take 10 days to reach its peak- **162996**

total deaths with additive etc model assuming it will take 15 days to reach its peak- **280068**

total deaths with additive etc model assuming it will take 20 days to reach its peak- **404939**

total deaths with multiplicative etc model assuming it will take 10 days to reach its peak- **185368**

total deaths with multiplicative etc model assuming it will take 15 days to reach its peak- **335326**

total deaths with multiplicative etc model assuming it will take 20 days to reach its peak- **614004**

In optimistic scenario, if we get the peak in just 5 day so total deaths would be **99408** with additive and **103785 **with multiplicative model. The total death trend will be-
