A researcher interested in explaining the level of foreign reserves for the country of
Barbados estimated the following multiple regression model using yearly data spanning the
period 2001 to 2016:
FR-a+BOIL+YEXP+8FDI
Where FR = yearly foreign reserves ($000's), OIL = annual oil prices, EXP= yearly total
exports ($000's) and FDI = annual foreign direct investment ($000's). The sample of data
was processed using MINITAB and the following is an extract of the output obtained:
