title: how to calculate the performance using RMSE
body: <p>How do i calculate RMSE between true and imputed values of Iris dataset.</p>
  
  <p>I am generating 10% NA values in iris dataset.
  Later i am imputing and predicting those values using Amelia package.</p>
  
  <p>Now i need to caculate RMSE between original iris datset and the simulated iris dataset</p>
  
  <p>Here is my code : </p>
  
  <pre><code>library(Amelia)
  
  #load data
  data("iris")
  
  #produce 10% missing data 
  iris.mis &lt;- prodNA(iris, noNA = 0.1)
  #summary(iris.mis)
  
  #run amelia
  #m  – Refers to 2 imputed data sets
  #noms – keep nominal variables here
  
  amelia_imp &lt;- amelia(iris.mis, m=2, noms = "Species")
  
  #check imputed outputs
  amelia_imp$imputations[[1]]
  amelia_imp$imputations[[2]]
  </code></pre>
  
  <p>Thank you.</p>
