 This assumption can be modeled with a linear regression over $\mu_{v_w}$, with parameters that represent the bias to categorize a string as a word, $\alpha_{w}$, the effect of lexicality, $\beta_{lex_{w}}$, and the effect of log-frequency $\beta_{\mathit{lfreq}_{w}}$.
 
 \begin{equation}
-mu_{v_{w,n}} = \alpha_w + \mathit{lex}_n \cdot \beta_{lex_{w}} + \mathit{\mathit{lfreq}}_n \cdot \beta_{\mathit{lfreq}_{w}}
+\mu_{v_{w,n}} = \alpha_w + \mathit{lex}_n \cdot \beta_{lex_{w}} + \mathit{\mathit{lfreq}}_n \cdot \beta_{\mathit{lfreq}_{w}}
 \end{equation}
 
 For the non-word accumulator, the location for the rate of accumulation of evidence is defined similarly:
 
 \begin{equation}
-mu_{v_{nw,n}}= \alpha_{nw} + \mathit{lex}_n \cdot \beta_{lex_{nw}} + \mathit{lfreq}_n \cdot \beta_{\mathit{lfreq}_{nw}}
+\mu_{v_{nw,n}}= \alpha_{nw} + \mathit{lex}_n \cdot \beta_{lex_{nw}} + \mathit{lfreq}_n \cdot \beta_{\mathit{lfreq}_{nw}}
 \end{equation}

 <p>Bruno Nicenboim (<a href="https://bruno.nicenboim.me" class="uri">https://bruno.nicenboim.me</a>) is an assistant professor in the department of Cognitive Science and AI at Tilburg University, the Netherlands, where he is the principal investigator (PI) of the Computational Psycholinguistics research line. He started studying Electronic Engineering at the National University of Rosario, Argentina, then transitioned to Human Sciences and spent eight years in Israel, where he completed a Bachelor’s degree in Sociology and Linguistics and a Master’s degree in Linguistics at Tel Aviv University. During this time, he also worked in several IT companies. He then moved to Germany, where he completed a PhD in Cognitive Science at the University of Potsdam and worked for two years as a postdoctoral researcher. His research interests include Bayesian methods, computational cognitive modeling, sentence comprehension, memory processes, decision making, and predictive processing. He regularly teaches short courses on Bayesian data analysis at workshops and summer schools, and he teaches Bayesian modeling and statistics courses in the master’s programs Cognitive Science &amp; AI and Data Science and Society at Tilburg University.</p>
