popmid

<p>Vector of population distribution that sums to 1.</p>

<p><code>popmid</code> calculates the cumulative midpoints for population percentiles that can then be used as the
  predictor in the OLS model for calculating the slope, i.e. the slope index of inequality (SII).
  For internal use within the <code>rii</code> function.</p>

internal

Tools for calculating deprivation measures and analysing health outcomes and mortality by deprivation.
Included are the functions: zscore() and w_pcntile() for developing deprivation measures and the functions smr(),
st_rate() and rii() for calculating standardized mortality ratios, direct standardized rates and Slope and Relative
indices of Inequality (SII and RII). Test data is included (dep_data and health_data).
The RII/SII are calculated following Pamuk ER (1985) <doi:10.1080/0032472031000141256>.
The confidence intervals for SII/RII are calculated using a multinomial distribution as described in Lumme et al (2015)
<doi:10.1007/s10742-015-0137-1>.
