ntp_jonckeere 
Jonckherre's test for significant differences from background dose

Toxicology routines for analyzing dose-response data include dose-response analysis
and trend tests. Dose-Response methods are based upon the US EPA's benchmark dose software 3. Methods have
been extended to include additional functionality based on World Health Organization
guidelines. It further supports the European Food Safety Authority's
draft guidance on model averaging. The dose-response methods and datasets used in this package are
described in Wheeler et al. (2019) <doi:10.1111/risa.13218>, Wheeler et al. (2020) <doi:10.1111/risa.13537>,
and Wheeler et al. (2022) <doi:10.1002/env.2728>. NTP routines are described in
Bailer and Portier (1988) <doi:10.2307/2531856>, Bieler and Williams (1993) <doi:10.2307/2532200>,
Williams (1971) <doi:10.2307/2528930>, and Shirley (1977) <doi:10.2307/2529789>.

ntp_jonckeere function

<dl><dt>formula</dt>
<dd>An equation of the form \(Y \sim X.\) Here the variable
\(Y\) is the response of interest, and \(X\) represents discrete experimental 
conditions. For example, if weight is the dependent variable, and you are
interested in looking at the trend across sex one would have 'weight ~ sex'.</dd>
<dt>data</dt>
<dd>A data frame with column names in the formula.</dd>
<dt>dose_name</dt>
<dd>The name of the variable containing the doses in the data frame \(data\).
It is expected multiple doses for each of the experimental conditions \(X\).</dd>
<dt>pair</dt>
<dd>The type of test used for pairwise comparison. It can either be
"Williams" or "Shirley"</dd></dl>
