Result
Fits a linear regression
model to Xlistname and
Ylistname with frequency
freqlist, and stores the
regression equation to
regequ.
Performs a linear
regression and a t-test.
L
alternative= 1 is <;
ƒ
alternative=0 is ;
alternative=1 is >.
Performs a linear
regression and computes
the t confidence interval for
the slope coefficient b.
Returns a list containing
the differences between
consecutive elements in
list.
Fills matrixname column by
column with the elements
from each specified
listname.
Returns the natural
logarithm of a real or
