%HEAD{ NAME="Simon Vandekar, !PhD" AFFILIATION="Vanderbilt University Medical Center" TITLE="Some New Developments for Neuroimaging Inference Using the PBJ R Package" IMAGELINK="https://www.vumc.org/biostatistics/sites/default/files/people/thumbnail_image001.jpg" }% Spatial extent inference (SEI) is widely used across neuroimaging modalities to study brain-behavior associations that inform our understanding of disease. Recent studies have shown that Gaussian random field (GRF) based tools can have hugely inflated family-wise error rates (FWERs). We developed a semiparametric bootstrap joint (sPBJ) testing procedure to address the limitations of available methods; our approach is the image equivalent of a robust sandwich covariance estimator and yields consistent estimates of standard errors, even under model misspecification. %TAIL{DATE="02 September 2020"}% <!-- * Set HEAD = <br> <br> <br> <div class="w3-card-2" id="task" style="max-width:750px; margin-left: 0px;"> <header class="w3-container w3-blue" style="padding:40px"><h1>Biostatistics Weekly Seminar</h1><br><h2 style="color:white;">%TITLE%<br><br>%NAME%<br>%AFFILIATION%</h2></header><div class="w3-container" style="padding:40px"><IMG SRC=%IMAGELINK% align="left" id="mug"/> * Set TAIL = <br><h3>Zoom (Link to Follow)<br>%DATE%<br>1:30pm</h3></div></div><br> --> <style> .w3-card-2,.w3-example{box-shadow:0 2px 4px 0 rgba(0,0,0,0.16),0 2px 10px 0 rgba(0,0,0,0.12)!important} .w3-blue,.w3-hover-blue:hover{color:#fff!important;background-color:#2196F3!important} .w3-container{padding:0.01em 16px} .foswikiTopic {font-family: 'Open Sans', sans-serif;} /* Removes location hierarchy (usually written in grey text) */ .patternHomePath {display:none;} /* Removes bar with edit and attach buttons and location hierarchy */ .patternTop{display:none;} h1, h2, h3, h4, h5, h6{font-family: 'Montserrat','Open Sans', sans-serif;font-weight:700;} h1, h2, h3, h4, h5, h6{color:#bf1735;} h1:first-of-type{color:#2a3e6e;margin-bottom:25px;margin-top:5px;} .foswikiImage{margin-left:-9px;} img#mug{padding-right: 40px; padding-bottom:25px; height:250px;} </style>
