Confidence interval for a correlation coefficient 
-------------------------------------------------

   ^z_rcii^ #obs r  [^,^ ^l^evel^(^cilevel^)^] 


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

^z_rcii^ is an immediate-form command to calculate confidence limits for product-
moment correlation coefficients.  It uses the Fisher z-transform to construct a
confidence interval, from a sample correlation ^r^ based on ^#obs^ observations.


Options
-------

^level(cilevel)^ sets the confidence level for the confidence interval requested.
    The default cilevel is 95%; values for cilevel may be specified as frac-
    tions, level(.975), or as percentages, level(97.5).


Examples
--------

 . ^z_rcii 84 .683^
   (95% confidence interval based on a sample of size n = 84 observations in
   which the product-moment correlation r = .683)

 . ^z_rcii 84 .683, level(99)^
   (the same as the previous example, except with confidence = 99%)


 . ^z_rcii 84 .683, l(.99)^
   (exactly the same as the previous example)
