Thanks as always to Kit Baum, a new version of the -eclplot- package is now available for download from SSC. In Stata, use the -ssc- command to do this, or -adoupdate- if you already have an old version of -eclplot-.

The -eclplot- package is described as below on my website, and produces plots of estimates with confidence limits. The new version adds an option -baddplot()-, which is like the -addplot()- option, except that the additional plot specified is in the background (behind the extimates and confidence limits). So, if the user programs:

sysuse auto, clear;
collapse (min) min=weight (p25) p25=weight (p50) p50=weight (p75) p75=weight (max) max=weight
  if !missing(rep78),
eclplot p50 p25 p75 rep78, hori eplottype(scatter) rplottype(rbar)
  estopts(msize(4)) ciopts(barwidth(0.75))
  xtitle("Weight (minimum, maximum and percentiles 25, 50 and 75)")
  baddplot(rspike min max rep78, hori)

then -eclplot- will produce a quasi-confidence-interval plot, with the 50th percentiles as "estimates" and the 25th and 75th percentiles as "confidence limits", and with spikes in the background (behind the "confidence intervals"), recording the minimum and maximum.

The new -eclplot- also fixes an old issue, where the SSC version of -eclplot- had the old Stata Version 9 on-line help file -eclplot.hlp-, instead of the up-to-date Stata Version 10 on-line help file -eclplot.sthlp-, documenting the -addplot()- and -baddplot()- options. However, the old Stata Version 8 -plot()- option still works for -eclplot-.

Best wishes (and Happy New Year)

      eclplot: Horizontal and vertical confidence interval plots

eclplot creates a plot of estimates with lower and upper confidence limits on one axis against another numeric variable on the other axis. The estimates and lower and upper confidence limits are stored in three variables, in a data set with one observation per confidence interval to be plotted. Data sets with such variables may be created manually (using a spreadsheet), or using the parmest package, or using statsby or postfile in official Stata. The user has a choice of plotting the confidence intervals horizontally or vertically, a choice of plot styles for the estimates, and a choice of range plot styles for the confidence intervals. It is also possible to overlay the confidence interval plot with other plots using the plot() option, and to overlay multiple superimposed confidence interval plots using the supby() option. eclplot may be used either as a command or through a dialog.
