From floated to conventional confidence intervals

    ftocci rrf {lbf ubf | sef} [, ref(#) format(%fmt) level(#)
              generate(newvar1 newvar2 newvar3) ]

    where the

    rrf point estimate of the relative risk

    is followed by

    lbf lower bound of the floated confidence interval
    ubf upper bound of the floated confidence interval

    or by

    sef floated standard error of the log relative risk

Description

    ftocci back calculates the conventional confidence intervals from
          the floated confidence intervals or from the floated
          standard errors of a set of relative risks.

Options

    ref(#) specifies the reference exposure category. Default is the first
        line.

    format(%fmt) specifies the display format for presenting numbers.
        format(%3.2f) is the default; see help format.

    level(#) specifies the width of the published floated confidence
        interval; see help level. The default level is 95%.

    generate(newvar1 newvar2 newvar3) specifies that the displayed results
        (conventional relative risk and confidence limits) to be saved in
        newvar1, newvar2 and newvar3 respectively.
