WebNow the log return method breaks down since the natural log cannot be taken for a negative number (unless imaginary numbers are used) log return = ln (1 - 1.1) = -2.30259 + 3.14159 i The curve for ln (x) is only in the positive domain of x. image source Share Improve this answer Follow edited Jan 16, 2016 at 20:56 answered Jan 16, 2016 at 20:31 WebWhy can't logarithms be negative? While the value of a logarithm can be a negative number, the argument (x-value) of any logarithm cannot be negative. This is because the base of a logarithm can only be a …

WebIf the base of the logarithm is negative, then the function is not continuous. For instance, sure the logarithm is defined for even and odd powers of negative numbers (though … WebYou are correct that when x = -8, the expression (x + 4) becomes negative, which is not valid because the logarithm of a negative number is undefined.

WebApr 27, 2011 · In the SAS/IML language, this transformation is easily programmed in a single statement. The following example uses b=1 and calls the LOG10 function, but you can call LOG, the natural logarithm function, if you prefer. proc iml; Y = {-3,1,2,.,5,10,100}; /* negative datum */ LY = log10 (Y + 1 - min (Y)); /* translate, then transform */ WebNo, that’s not right: no matter what the base b, log b x is not defined for x ≤ 0. Recall that log b x = y means that b y = x. If b > 0 and b ≠ 1, no power of b is negative or 0, so the equation b y = x has no solution for x ≤ 0. We don’t define logs base b for b = 1 or b ≤ 0.
