As Mikee N says,
if(fit function < definite & evaluations <3 & free parameters > 0){ message("your starting values are too far off reality for me find my way home... You might try setting the means to their actual values (that often flumoxes me), and perhaps get the covariances closer to realistic values for me, but certainly start by setting each variable's mean to its actual value to give me a hint..." }
re mxTryHard()
Would it be wise to set scale to .05 by default?
Should mxTryHard (optionally?) set means to the phenotypic value?
