Important: Read this before posting to this forum

  1. This forum is for questions related to the use of Apollo. We will answer some general choice modelling questions too, where appropriate, and time permitting. We cannot answer questions about how to estimate choice models with other software packages.
  2. There is a very detailed manual for Apollo available at http://www.ApolloChoiceModelling.com/manual.html. This contains detailed descriptions of the various Apollo functions, and numerous examples are available at http://www.ApolloChoiceModelling.com/examples.html. In addition, help files are available for all functions, using e.g. ?apollo_mnl
  3. Before asking a question on the forum, users are kindly requested to follow these steps:
    1. Check that the same issue has not already been addressed in the forum - there is a search tool.
    2. Ensure that the correct syntax has been used. For any function, detailed instructions are available directly in Apollo, e.g. by using ?apollo_mnl for apollo_mnl
    3. Check the frequently asked questions section on the Apollo website, which discusses some common issues/failures. Please see http://www.apollochoicemodelling.com/faq.html
    4. Make sure that R is using the latest official release of Apollo.
  4. If the above steps do not resolve the issue, then users should follow these steps when posting a question:
    1. provide full details on the issue, including the entire code and output, including any error messages
    2. posts will not immediately appear on the forum, but will be checked by a moderator first. This may take a day or two at busy times. There is no need to submit the post multiple times.

How to calculate 95% confidence level?

Post by Chunyu Song »

Dear all,

I ran my model (LCNL) and calculated the WTP using apollo_deltaMethod. Now I want to obtain the 95% confidence intervals for each estimated parameter and the WTP values, but I don't know how to calculate them.

Could you please give me an example (code syntax)? Many thanks!


Best wishes,
Chunyu Song.

Hi Chunyu

sorry for the slow response.

you can calculate asymptotic confidence intervals by the simple formula

estimate +- 1.96 * standard error

You can do this directly for estimates, and for things like WTP, you can get the value and standard error using apollo_deltaMethod and then apply the formula above
