In this paper, the Box-Jenkins
Autoregressive Integrated Moving Average (ARIMA)
models for active and exponential smoothing HOLT for
removed rates has been estimated using daily time
series data from 1st April to 14thSeptember 2020.The
active and removed rates are computed from
cumulative confirmed, active, recovered and deceased
cases. It has been found that ARIMA (0, 1, 1) and Holt
exponential smoothing Models are best fit for active and
removed rates respectively. Normalized BIC is 0.577and
0.898 for active and removed rates respectively and is
minimum among all the six models considered. Lack of
fit of models is tested by Ljung-BoX Q statistic. The pvalue is 0.925 and 0.840 for active and removed rates
respectively Since for both the rates p-value is greater
than 0.05, hence conclude that our model does not show
a lack of fit. On the basis of our analysis, active rate will
be nullified latest by 5th January 2020, if everything
goes best, as P M of India has assured on eve of
Independence Day that vaccine for corona will be
available very soon. Otherwise by 9
th February 2021 if
the past trend continued and in worst situation it will
tends to zero on 26th March 2021. We expect the
removed rates will reach 100 percent by 20TH October
2020 if everything goes best and by 5th January 2021 if
the past trend continued. On the assumptions that
Pandemic will come to an end when removed rate in the
population tends to 100 percent and active rate to zero
percent. Thus on the basis our analysis we expect that
COVID – 19 Pandemic may come to end latest either by
9
th February 2021 or 26th March 2021 subject to
condition that the social distance and safely measures
remains vigilance to stabilize and control the pandemic
and in achieving India’s recovery from COVID-19.
