The curve estimates
The study made use of curve estimate regression models to plot the
relationship of paid-up shares and number of members. Specifically,
linear, quadratic and cubic were used to identify the appropriate model
to measure the correlation of the paid-up shares and number of members.
A 7-year panel data series were used as an input in generating curve
estimations. The graphs made use of the trial version of the Statistical
Package for the Social Sciences (SPSS) which was then analyzed and used
for interpretation.
