Result
Returns the reduced row-echelon form of a matrix.
Returns R, given rectangular coordinates x and y or a list
of rectangular coordinates.
Returns q , given rectangular coordinates x and y or a list of
rectangular coordinates.
Û
Performs a two-sample
alternative=0 is ƒ ; alternative=1 is >. drawflag=1 draws
results; drawflag=0 calculates results.

results; drawflag=0 calculates results.
Computes a two-sample t confidence interval. pooled=1
pools variances; pooled=0 does not pool variances.
