title: Logit-Transformation backwards
body: <p>I've transformed some values from my dataset with the <code>logit</code> transformation from the car-package. The variable "var" represent these values and consists of percentage  values. </p>
  
  <p>However, if I transform them back via <code>inv.logit</code> from the boot-package, the values dont match the original ones.</p>
  
  <pre><code>data$var
  46.4, 69.5, 82.7, 61.7, 76.4, 84.8, 69.1
  
  data["var_logit"] &lt;- logit(data$var, percents=TRUE)
  
  data$var_logit
  -0.137013943, 0.778005062, 1.454239241, 0.452148763, 1.102883518, 1.589885549, 0.760443432
  
  data$var_logback &lt;- inv.logit(data$var_logit)
  0.46580 0.68525 0.81065 0.61115 0.75080 0.83060 0.68145
  </code></pre>
  
  <p>It looks like I have to multiply the result with 100 to get the previous values (or at least some very similar values), but I feel like I'm missing something.</p>
  
  <p>Thanks for the help!</p>
