Re: Original VPW Bug?

When I look at CFireSim's charts, the first year withdrawal varies based on the first year of retirement. This has me worried that you use the following spending model, instead: Assume were on the evening of December 31, 2014. I'm ready to retire tomorrow on Jan 1st, 2015. I have a $1,000,000 portf...

Re: cFIREsim Running Change Log

12-7-2014 - Version 2.0.17 - updated the stats functions and general simulation function. Previously, there was a workaround that allowed cFIREsim to show a "Start Year" of 2014 and an "End Year" of 2044 on the main page, and let the user assume that it was a 30 year simulation....

Re: Possible bug in median and average yearly withdrawal out

Hmmm you're right. I just updated the logic for determining the "Start Year" of retirement. There was a disconnect between a retirement starting this year (2014) and one starting in the future, because of how my code is setup. 2014 = Year 0 in my code. Hard to follow the difference without...

Re: Possible bug in median and average yearly withdrawal out

In your screenshot, the withdrawal analysis looks off to me. For the "first 5 years", shouldn't the average be (40k+40k)/5 = 16k Even better would be for it to use the actual number of withdrawal years if it's less than 5 so (40k+40k)/2 = 40k. Well, that is actually because the simulation...

Re: Possible bug in median and average yearly withdrawal out

Here is what I see now from a retirement that starts in 2015 and ends in 2016 (which is 2 years of retirement): http://imgur.com/fjZYFH2.png Under "Yearly Withdrawals", I see an average of $40,000 and a median of $40,000. This is consistent with what I would expect (FYI, all the numbers in...

Re: Possible bug in median and average yearly withdrawal out

Fixed on the main site. Looks like the "Number of Years" for a retirement was 1 short of what it should be. So, for a 2-year retirement, it would calculate all stats based on 1 year. In the case of your example, it would see $80,000 of total withdrawals, but instead of dividing by 2 to fin...

Re: cFIREsim Running Change Log

12-3-2014 - Version 2.0.16
- Updated stats.php, which is responsible for the statistics chart in the output page. The number of years for a retirement was being miscalculated by 1.

Re: Historical Data - Specific Years: one year too many

Just getting around to checking this. I did "Single Simulation Cycle" of 1965 and only got one line. Do you have a saved simulation ID that I can recreate from?

Re: Possible bug in median and average yearly withdrawal out

Interesting. I just recreated it. My guess is that there is a miscalculation in the years of the "stats" section of the code which produces this table.

If it's any consolation, I'm sure this isn't affecting the success %. I'll more thoroughly review this and report back. Thanks!
