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
Numeric view variables
C0...C9
Statistics 2Var
Contain lists of numerical data. In Numeric view, enter numerical data in C0 through C9.
In a program, type:
LIST ▶ Cn
where n = 0, 1, 2, 3 ... 9 and LIST is either a list or the name of a list.
D0...D9
Statistics 1Var
Contain lists of numerical data. In Numeric view, enter numerical data in D0 through D9.
In a program, type:
LIST ▶ Dn
where n = 0, 1, 2, 3 ... 9 and LIST is either a list or the name of a list.
