A Regression And Correlation Analysis Of The Effect Of Weather Component On The Yield Of Ginger (A Case Study Of National Root Crop Research Institute Umudike, Abia State)
ABSTRACT
The data used for this project work
was collected from National Root Crop Research Institute (NIRCRI) Umudike at
ginger unit and at metrological Unit for the weather parameterS from the year
2001 — 2010. The objectives of this project work was to construct a model which
can be used to predict the values of yield of ginger given the values of the
weather parameters, secondly, to measure the extent at which change in one or
more variable jointly affect change in another, thirdly, to determine whether
there is significant relationship between the dependent variable and a set of
all independent variable, lastly to test for the existence of
multicollinearityin a multiple regression model. In testing the significance of
the model, it was established at 5% level of significance that there exist a
functional relationship between the yield of ginger and weather parameters. I
equally test the multicollinearity for the explanatory variable which was revealed
that the variables were not perfectly correlated linearly. It was also
discovered that rainfall if not considered may not really affect the high yield
of ginger but temperature, Relative humidity and sunshine if not considered
will affect the high yield of ginger.
