Input Description
x2 The count of successes from sample two for the
2 . PropZTest and 2 . PropZInt . Must be an integer ‚ 0.
n1 The count of observations in sample one for the
2 . PropZTest
and
2 . PropZInt
. Must be an integer > 0.
n2 The count of observations in sample 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 given as a
percent and is divided by 100. Default=0.95.
Observed (Matrix) The matrix name that represents the columns and rows
for the observed values of a two-way table of counts for
the
c 2
. Test
.
Observed
must contain all integers ‚ 0. Matrix
dimensions must be at least 2×2.
Expected (Matrix) The matrix name that specifies where the expected
values should be stored.
Expected is created upon
successful completion of the c 2
. Test .
Xlist , Ylist The names of the lists containing the data for
LinRegTTest
.
Defaults are L1 and L2 , respectively. The dimensions of
Xlist and Ylist must be the same.
RegEQ The prompt for the name of the Y= variable where the
calculated regression equation is to be stored. If a
Y= variable is specified, that equation is automatically
selected (turned on). The default is to store the
