Time Series Analysis Of Number Of Children Immunized Against Polio Disease (A Case Study Of Isiala Ngwa North L.G.A) :- Henshaw Monica L
ABSTRACT
This study considered the time series analysis of
the number of children immunized against polio disease using Box-Jenkins
methodology. Time series plot of the data showed evidence of nonstationarity in
the series. The series became stationary after the first order differencing.
Both plots of the autocorrelation function and autocorrelation function for the
differenced series cut off at lag 1. ARIMA (1,1,1) was fitted to the series.
Plots of '. corresponding residual ACF and PACF behaved like those of i , l , t
a white noise process. This confirmed the adequacy of the series.
