LSIPLOT procedure

Plots least significant intervals, saved from SEDLSI (M.C. Hannah).

Options

WINDOW = scalar

Window in which to plot the graph

TITLE = text

Title for the graph; default 'Estimates with LSIs by Treatment'

YTITLE = text

Title for the y-axis; default 'Estimates'

Parameter

LSI = pointers

Defines the least significant intervals

Description

Least significant intervals (LSIs) are used for comparing a set of estimates (e.g. predicted means from ANOVA or regression) graphically, especially when their SEDs differ. LSIs are intervals (or error bars) that are designed to overlap where there is no significant difference between estimates, and to be disjoint (i.e. not to overlap) where there are significant differences.

LSIs can be calculated by the SEDLSI procedure and saved, in a pointer, using its LSI parameter. This pointer can then be be supplied as input to LSIPLOT, using its own LSI parameter, to plot the intervals on a later occasion.

LSIPLOT has an option WINDOW to specify the window in which to plot the LSIs. By default a window is defined internally, within LSIPLOT, to fill the whole screen. The TITLE option allows you to supply a title for the plot (default 'Estimates with LSIs by Treatment'), and the YTITLE option supplies a title for the y-axis (default 'Estimates').

Options: WINDOW, TITLE, YTITLE.

Parameter: LSI.
