Input Description
p
0
The ex
ected sam
le
ro
ortion for 1.PropZTest. Must be a
real number, such that 0 < p
0
< 1.
x The count of successes in the sam
le for the 1.PropZTest and
1.PropZInt. Must be an integer ‚ 0.
n The count of observations in the sam
le for the 1.PropZTest
and 1.PropZInt. Must be an integer > 0.
x1 The count of successes from sam
le one for the 2.PropZTest
and 2.PropZInt. Must be an integer ‚ 0.
x2 The count of successes from sam
le two for the 2.PropZTest
and 2.PropZInt. Must be an integer ‚ 0.
n1 The count of observations in sam
le one for the 2.PropZTest
and 2.PropZInt. Must be an integer > 0.
n2 The count of observations in sam
le two for the 2.PropZTest
and 2.PropZInt. Must be an integer > 0.
C.Level The confidence level for the interval instructions. Must be ‚ 0
and <100. If it is ‚ 1, it is assumed to be
iven as a
ercent and
is divided by 100. Default=0.95.
Observed (Matrix) The matrix name that re
resents the columns and rows for the

table of counts for the
2
.Test.
Observed must contain all inte
ers ‚ 0. Matrix dimensions must
e at least 2×2.
Expected (Matrix) The matrix name that s
ecifies where the ex
ected values
should be stored. Expected is created u

completion of the c
2
.Test.
Xlist, Ylist The names of the lists containin
the data for LinRegTTest.
Defaults are L1 and L2, res
ectivel

re
ression e
uation is to be stored. If a Y= variable is s
ecified,
that e
uation is automaticall
selected
turned on
