Time Series Analysis On The Internally Generated Revenue, In Imo State Of Nigeria From 2001-2005
ABSTRACT
This study has mainly exposed the
mathematical and statistical methods involved in time series analysis with
particular reference to the revenue income of Imo State Nigeria from 2001 to
2005. In our tests, using chi-square statistics, I tested for equality of
variances at 5% significance level and concluded that revenue collections are
not equally collected and tested for independence at 1% significant level and
concluded that revenue collections depends on time. We use the multiplicative
method to analyze the data. During the course of this analysis, the four
components of time series-were assumed and the decomposition method was applied
to isolate the four components for separate analysis. The decomposition shows
from the trend equation that collection has been increased by N2.O1 per month.
The trend equation is given by t=33.27+2.01(t),t=12, ...,60. Cyclical
influences was also detected. Revenue collection is the highest during the
eleventh month, the seventh is the least, the irregular components as we
expected are randomly distributed. The data was also depersonalized to remove
the effect of the seasonal variation. Forecast was made for 2006. Finally,
useful recommendations were made to faster better revenue collections.
