For a regional status assessment, the status of each time series is summarised by the difference between the estimated mean log concentration in the final monitoring year and the log assessment concentration.  This ensures that status is always measured on the same scale, even though the assessment criterion might vary between `r detLabel`s and time series.  Essentially the same linear mixed model as for trends is then fitted:
</p>


```{asis, echo = detFixedEffect}
<ul type = "disc">
<li>response: status (mean log concentration - log assessment concentration)</li>
<li>fixed model: region * `r detLabel`</li>
<li class = "last">random model: station + status estimation variation + residual variation</li>
</ul>

<p class = "botbig">
where status estimation variation is the variation in the status estimates from the individual time series analysis, assumed known and fixed.
</p>
```

```{asis, echo = !detFixedEffect}
<ul type = "disc">
<li>response: status (mean log concentration - log assessment concentration)</li>
<li>fixed model: region</li>
<li class = "last">random model: `r detLabel` + region.`r detLabel` + station + status estimation variation + residual variation</li>
</ul>

<p class = "botbig">
where status estimation variation is the variation in the status estimates from the individual time series analysis, assumed known and fixed.  
</p>
```

<p class = "botbig">
There are no restrictions on the time series used in the status meta-analysis based on the classification of the monitoring station; time series from baseline, representative and impacted stations are all included. However, the few time series with a non-parametric assessment of status must be excluded, because there is no summary measure of status to use in the mixed model.   
</p>

```{asis, echo = detFixedEffect}
<p class = "botbig">
Again, the meta-analysis is restricted to regions and `r detLabel` combinations with at least three status stations with good geographic spread. 
</p>
```

```{asis, echo = !detFixedEffect}
<p class = "botbig">
Again, the meta-analysis is restricted to regions with at least three status stations with good geographic spread and to `r detLabel`s with status information for at least three stations (over all regions).
</p>
```
