risk of ruin for sngs

[baztalkspoker]

I wish to work out my ROR percentages for sngs but i need to know how to figure my standard deviation for sngs. Anyone know how to derive this?

Was my question an unreasonable one that it merited a taking the p1ss answer [img]/images/graemlins/confused.gif[/img]

if u 're a winner, and manage ur br well (100 buyins, move down if need be etc) your ror is effectively 0


as obviosly shown in the above post

It's a pretty simple calculation. x_bar = you average payout per sng. xi = you payout for each individual sng when you've played N sngs.

So, you play 5 sngs and you payouts are:

300
100
0
-100
200

N = 5.
x_bar = (300+100+0-100+200)/5 = 100

summation:

(300-100)^2 + (100-100)^2 + (0-100)^2 + (-100-100)^2 + (200-100)^2 = 100 000.

stand dev = (1/5*100 000)^1/2 = 141.4

If you go to Sharkscope and export all of your results to an Excel sheet, I have a Data Analysis plug-in for Excel that will let me calculate the SD, among other things. PM me for my email address.

Why do people feel the need to give these type of answers. [img]/images/graemlins/confused.gif[/img] If you're not interested in the question fair enough but there really is no need for sarcasm imo.
