title: Testing differences between conditions (in R)
body: <p>I have a data frame &quot;test&quot; and several variables:</p>
  <p>&quot;eco&quot; = 0, 1</p>
  <p>&quot;gender&quot; = 0, 1</p>
  <p>&quot;age&quot; in years</p>
  <p>How could I test whether gender and age differ between the &quot;eco = 0&quot; and &quot;eco = 1&quot; conditions? I assume that Linear Probability model needs to be used.</p>
