title: Error in pglm (fixed - within, between data panel model)
body: <p>I'm trying estimate a logit data panel using a between and within model. However is occurring the follow error:</p>
  <p>Error during wrapup: argument &quot;start&quot; is missing, with no default
  Error: no more error handlers available (recursive errors?); invoking 'abort' restart</p>
  <p>below, follow the code:</p>
  <p>Logit_between &lt;- pglm(Treat ~ Size_win  + ROE_win + Age_win + IndCAdm_win + Lev_win + factor(Prej) + factor(Constr) + factor(CC) + factor(TI)+ factor(Telec)+ factor(UP), family = binomial('logit'), model = 'between', data=Base_PAS_Final, index = c(&quot;Id&quot;, &quot;Year&quot;), start=NULL, method = &quot;bfgs&quot;, print. Level = 3, R = 5)</p>
  <p>Treated = Dummy variable (1 for the companies that suffered lawsuits, 0 no suffered)
  Size, ROE, Age,IndCAdm and Levarage are continuous variables.</p>
  <p>Constr, CC, TI, Telec, and UP are dummies that control the industry effect.</p>
  <p>Anyone had this problem or can help me about it?</p>
