Confidence intervals for correlations
-------------------------------------

	^ci2^ varname1 varname2 [^if^ exp] [^in^ range] [weight] [^,^ ^l^evel^(^#^)^
                                {^co^rr ^sp^earman} ]

	^cii2^ #n #r [^,^ ^l^evel^(^#^)^ ^co^rr]


Description
-----------

Without the ^corr^ or ^spearman^ options, ^ci2^ and ^cii2^ behave as @ci@ and
@cii@.

^ci2^ calculates correlations and produces confidence intervals for a single
correlation, based on Fisher's transformation.  As with @correlate@, ^ci2^
takes frequency and analytic weights.

With option ^spearman^, the confidence interval is based on Spearman's rank correlation.

^cii2^ is the immediate version.


Examples

  . ^ci2 colorime icp , corr^
  . ^cii2 78 .52 , corr^			(78 paired observations, correlation 0.52)


  . ^ci2 mpg^
  . ^ci2 mpg price, level(90)^
  . ^ci2 promoted, binomial^
  . ^ci2 count, poisson^
  . ^ci2 deaths, exposure(pyears)^

  . ^cii2 166 19509 4379^                 (166 obs, mean=19509, sd=4379)
  . ^cii2 166 19509 4379, level(90)^
  . ^cii2 10 1^                           (10 binomial events, 1 observed success)
  . ^cii2 1 27, poisson^                  (27 Poisson events observed)
