The econometric universe is infinite and expanding, so we ask that questions be brief and relate to material in the book. Here is an example:</p> 156<p>“In Section 8.2.3, (on page 319), you suggest that 42 clusters is enough for the usual cluster variance formula to be fairly accurate. Is that a joke, or do you really think so?”<br /> 157To which we’d reply: “Yes.”</p> 158<p><!-- ddfm1 --></p> 159 160 161 162 </div> 163 </div><!-- .post --> 164 165 166 167 </div><!-- #content --> 168 </div><!-- #container --> 169 170 171<div id="primary" class="aside main-aside"> 172 <ul class="xoxo"> 173<li id="text-430748541" class="widgetcontainer widget_text"> <div class="textwidget"><h3><a href="/wordpress/blog/question">Ask a Question</a></h3> 174 175<h3><a href="/wordpress/blog/correction">Send a Correction</a></h3> 176 177<h3><a href="/wordpress/blog/comment">Post a Comment</a></h3> 178 179</div> 180 </li><li id="mhe_widget_tag_cloud" class="widgetcontainer mhe_widget_tag_cloud"><h3 class="widgettitle">Tags</h3> 181<ul class='wp-tag-cloud' role='list'> 182 <li><a href="https://www.mostlyharmlesseconometrics.com/tag/corrections/" class="tag-cloud-link tag-link-12 tag-link-position-1" style="font-size: 13px;">Corrections</a></li> 183 <li><a href="https://www.mostlyharmlesseconometrics.com/tag/difference-in-differences/" class="tag-cloud-link tag-link-19 tag-link-position-2" style="font-size: 13px;">difference-in-differences</a></li> 184 <li><a href="https://www.mostlyharmlesseconometrics.com/tag/fixed-effects/" class="tag-cloud-link tag-link-17 tag-link-position-3" style="font-size: 13px;">fixed effects</a></li> 185 <li><a href="https://www.mostlyharmlesseconometrics.com/tag/laggged-dependent-variable/" class="tag-cloud-link tag-link-18 tag-link-position-4" style="font-size: 13px;">laggged dependent variable</a></li> 186 <li><a href="https://www.mostlyharmlesseconometrics.com/tag/questions/" class="tag-cloud-link tag-link-16 tag-link-position-5" style="font-size: 13px;">Questions</a></li> 187 <li><a href="https://www.mostlyharmlesseconometrics.com/tag/reader-comments/" class="tag-cloud-link tag-link-13 tag-link-position-6" style="font-size: 13px;">Reader Comments</a></li> 188 <li><a href="https://www.mostlyharmlesseconometrics.com/tag/regression-discontinuity/" class="tag-cloud-link tag-link-20 tag-link-position-7" style="font-size: 13px;">Regression Discontinuity</a></li> 189 <li><a href="https://www.mostlyharmlesseconometrics.com/tag/review/" class="tag-cloud-link tag-link-21 tag-link-position-8" style="font-size: 13px;">Review</a></li> 190</ul> 191</li> <li id="mhe_widget_recent_entries" class="widgetcontainer mhe_widget_recent_entries"> <h3 class="widgettitle">Recent Posts</h3> 192 <ul> 193 <li><a href="https://www.mostlyharmlesseconometrics.com/2019/07/mhe-wins-the-fama-prize/">MHE Wins the Fama Prize! </a></li> 194 <li><a href="https://www.mostlyharmlesseconometrics.com/2015/07/a-fundamentally-sensible-question/">A Fundamentally Sensible Question </a></li> 195 <li><a href="https://www.mostlyharmlesseconometrics.com/2015/06/just-a-little-off/">Just a little off </a></li> 196 <li><a href="https://www.mostlyharmlesseconometrics.com/2015/02/random-thoughts/">Random Thoughts </a></li> 197 <li><a href="https://www.mostlyharmlesseconometrics.com/2015/02/mhe-p-13-t-stats/">MHE p. 13 t-stats </a></li> 198 </ul> 199 </li> 200 </ul> 201</div><!-- #primary .aside --> 202 203<div id="secondary" class="aside main-aside"> 204 <ul class="xoxo"> 205 <li id="rss-links" class="widgetcontainer widget_thematic_rsslinks"> <h3 class="widgettitle">RSS Links</h3> 206 <ul> 207 <li><a href="https://www.mostlyharmlesseconometrics.com/feed/" title="Mostly Harmless Econometrics Posts RSS feed" rel="alternate nofollow" type="application/rss+xml">All posts</a></li> 208 <li><a href="https://www.mostlyharmlesseconometrics.com/comments/feed/" title="Mostly Harmless Econometrics Comments RSS feed" rel="alternate nofollow" type="application/rss+xml">All comments</a></li> 209 </ul> 210 </li> 211 </ul> 212</div><!-- #secondary .aside --> 213 214 </div><!-- #main --> 215 216 217 218 <div id="footer"> 219 220 221 <div id="siteinfo"> 222 223 224 </div><!-- #siteinfo --> 225 226 227 </div><!-- #footer --> 228 229 230 231</div><!-- #wrapper .hfeed --> 232
