The problem of determining the estimability of linear parametric
functions in classification models is examined. The two estimability
problems which are specifically aimed at are: the problem of determining
whether the design matrix is of maximal rank (i. e. , all cell
expectations are estimable); and in the event that...
Graph production by computer requires a blending of
human effort in scale selection with computer precision in
datum point placement. Existing techniques are designed
primarily for computer scientists; the average scientific
investigator, educator, or businessman tends to avoid them
for one or more of the following reasons: expense, complexity,
or...
