The analyst uses computer software to estimate the parameters of the logistic regression model. The G statistic for the test of overall signicance
has 3 V degrees of freedom. If the value of the G test statistic is 3.25, its p-value is .0411 V . At signic

Macroeconomics is the study of the economy as a whole. A macroeconomic variable is one that measures a
characteristic of the whole economy or one of its large-scale sectors. In forecasting the sales of a p
The multiple coefficient of determination, denoted R2, is the ratio of the sum of squares clue to regression J to
the total sum of squares \l . The R2 for the new regression is 0.52 \l , indicating that the new
estimated multiple regression equation expla
The mean square due to error divided by the total mean square is 0.55 J , and 1 minus this ratio is 0.45 J .

In mathematics, we often come across powers.
(a.b)n = anbn
anam = an+m
(an)m = anm
(a/b)n = an/bn
(1/an) = a-n
a0 = 1
