Time Series Analysis Of Number Of Children Immunized Against Polio Disease (A Case Study Of Isiala Ngwa North L.G.A) :- Henshaw Monica L

Projects

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.
