Function Definitions
Median
Ranks
The Median Ranks function returns any median rank. The two inputs required are
the sample size and the order number. All inputs should be put in their
respective input boxes as specified by the current window. The median rank
returned is obtained by solving for the following equation for Z,
Where N
is the sample size, and j is the order number.
Other
Ranks
The Other Ranks function is similar to the Median Ranks
function, but it allows you to get a rank at any percentage point instead of
only at the 50% point.
The rank can be
found for any percentage point, P, greater than zero and less than one,
by solving the following equation for Z,
where N is
the sample size and j is the order number.
Standard
Normal Tables
The Standard Normal Tables function is defined by,
The only input is
x.
Inverse
Standard Normal Tables
The Inverse Standard Normal Tables function is defined by:
The required input
is t.
Cumulative
Poisson
The Cumulative Poisson function returns values for the cumulative Poisson
distribution, as defined next,
where the required
inputs are 
and the upper bound on the summation, n.
Cumulative
Binomial Probability
The Cumulative Binomial Probability returns values for the cumulative binomial
probability, as defined next,
where the required
inputs are the starting and ending points of the summation, k and n, and the
percentile, P.
F-Distribution
Values
The F-Distribution function returns the value of 
as defined next,
For (F ³ 0), and
B representing the beta function. The required inputs are the value of F and the
two degrees of freedom, 
and 
.
Inverse
F-Distribution Value
The Inverse F-Distribution function returns values as defined for the F-Distribution.
The required
inputs are ,
and .
Chi-Square
Values
The Chi-Square Probability function returns values as defined next,
The required
inputs are the values of d, v and 
.
Incomplete
Beta Function
The Incomplete Beta Function returns the value of 
as defined next,
where (0 < x
< 1).
The required inputs are the values of x, a and b.
Gamma
Function
The Gamma Function option returns values as defined next,
for (x > 0), or
for (0 > x 
-1, -2, -3,...).
The only input required is x. The program returns the value of G(x).
Student's
t Values
The Student’s t Values function returns values as defined next,
The required
inputs are the values of a, v and t.
