    Trivariate CDF, solving for variable within CDF itself?

    Ok, I apprec the advice. I've decided to tweak my original project idea a bit and work with the formula as is. So I will input injury force, and keep ramping that up until my probability of injury is >.5. Would that be possible? And if so, any tips on tackling it? Right now, in Excel, I have...

    Trivariate CDF, solving for variable within CDF itself?

    Hm.. interesting points. @bpet - that's correct, I'm looking at a normal distribution CDF @Stephen Tashi - The original eqn I'm working from is a probability distribution function of injury, taking into account force, age, and mass. I have probability curves from this, plotting force vs...

    Trivariate CDF, solving for variable within CDF itself?

    So I've spent the better part of the last 2 days reading your forums (awesome btw) as well as as scouring Google and other sites for the past week, trying to figure out what to do. I have this equation here: p(injury) =\Phi \frac{ln(F) - 2m - 3a + b}{0.8} probability(injury) =...
