logdiff: logdiff
In jennasimit/MTFM: Multinomial fine-mapping

Internal function, logdiff

1	logdiff(x, y)

`x`	numeric
`y`	numeric

This function calculates the log of the difference of the exponentiated logs taking out the max, i.e. insuring that the difference is not negative

ie you want log(exp(x) - exp(y))

max(x) + log(exp(x - max(x,y)) - exp(y-max(x,y)))

x <- 1001:1010
y <- 1:10
log(x-y)
MFM:::logdiff(log(x),log(y))
