Programming in HP PPL 311
With Method=1, the constants and their meanings are as
follows:
0 Z-Int:1
1 Z-Int:
2 Z-Int:1
3 Z-Int:
4 T-Int:1
5 T-Int:
With Method=2, the constants and their meanings are as
follows:
0 Chi-square goodness of fit test
1 Chi-square two-way test
With Method=3, the constants and their meanings are as
follows:
0 Linear t-test
1 Interval: Slope
2 Interval: Intercept
3 Interval: Mean Response
4 Prediction Interval
X0, Y0...X9,Y9
Parametric
Contains two expressions in T: X(T) and Y(T). In
Symbolic view, select any of X0–Y0 through X9–Y9 and
enter expressions in T.
In a program, store expressions in T in Xn and Yn, where
n is an integer from 0 to 9.
Example:
SIN(4*T) 
Y1;2*SIN(6*T)

X1
U0...U9
Sequence
Contains an expression in N. In Symbolic view, select any
of U0 through U9 and enter an expression in N, Un(N-1),
or Un(N-2).
In a program, use the RECURSE command to store the
expression in Un, where n is an integer from 0 to 9.
Example:
RECURSE (U,U(N-1)*N,1,2)  U1
