Input Description
p
0
The ex
p
ected sam
p
le
p
ro
p
ortion for 1.PropZTest. Must be a
real number, such that 0 < p
0
< 1.
x The count of successes in the sam
p
le for the 1.PropZTest and
1.PropZInt. Must be an integer ‚ 0.
n The count of observations in the sam
p
le for the 1.PropZTest
and 1.PropZInt. Must be an integer > 0.
x1 The count of successes from sam
p
le one for the 2.PropZTest
and 2.PropZInt. Must be an integer ‚ 0.
x2 The count of successes from sam
p
le two for the 2.PropZTest
and 2.PropZInt. Must be an integer ‚ 0.
n1 The count of observations in sam
p
le one for the 2.PropZTest
and 2.PropZInt. Must be an integer > 0.
n2 The count of observations in sam
p
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
g
iven as a
p
ercent and
is divided by 100. Default=0.95.
Observed (Matrix) The matrix name that re
p
resents the columns and rows for the
observed values of a two-wa
y
table of counts for the
c
2
.Test.
Observed must contain all inte
g
ers ‚ 0. Matrix dimensions must
b
e at least 2×2.
Expected (Matrix) The matrix name that s
p
ecifies where the ex
p
ected values
should be stored. Expected is created u
p
on successful
completion of the c
2
.Test.
Xlist, Ylist The names of the lists containin
g
the data for LinRegTTest.
Defaults are L1 and L2, res
p
ectivel
y
. The dimensions of Xlist
and Ylist must be the same.
RegEQ The
p
rom
p
t for the name of the Y= variable where the calculated
re
g
ression e
q
uation is to be stored. If a Y= variable is s
p
ecified,
that e
q
uation is automaticall
y
selected
(
turned on
)
. The default
is to store the regression equation to the
RegEQ variable only.
