7.3 Variable Creation
The function parameters are defined as:
regression_variable
a scalar variable which is the output of an earlier StatRegSpa()
function
function
the statistical quantity to return (0=sum of squares error, 1=sum of
squares total, 2=sum of squares model, 3=R-squared)

Statistics
Regression info
StatRegVal2 (any part(s), regression_variable, function, selection)
This function returns statistical diagnostics specific to individual input coefficients
for a regression computed using StatRegSpa(). The function is passed the output variable
of a previously computed StatRegSpa(), the function number of the specific statistical
quantity to return and the coefficient selected. The values include the sum of squares and
partial sum of squares for the individual coefficients as well as the estimated coefficient
itself and its standard error.
The function parameters are defined as:
regression_variable
a scalar variable which is the output of an earlier StatRegSpa()
function
function
the statistical quantity to return (0=the estimated coefficient, 1=sum
of squares for the variable, 2=partial sum of squares for the
variable, 3=standard error for the coefficient)
selection
constant variable or constant number which selects the specific
coefficient for which to retrieve the statistical quantity (0=x0, 1=x1,
2=x2, 3=x3, 4=x4)

Surface Integral
See Surface Integral under Integrals.
Computes a constant variable whose value is the integral of the input variable over
the surface of the specified 2D part(s).
Swirl
Swirl (any part(s), density, velocity).
Computes a scalar variable Swirl, whose value is:
V
Swirl = -------------V 2
where:  = vorticity
 = density
V = velocity
Temperature

gas constant)
Computes a scalar variable whose value is the temperature T defined as:
