log2 computes binary logarithms (Log2). I will also post the answer that our teacher says we should get.The answer I should get is 36.55539635919235 EXP(X) is the exponential function of X, so EXP(LN(X)) = X and LN(EXP(X)) = Apart from log() function, R also has log10() and log2() functions. These unique features make Virtual Nerd a viable alternative to private tutoring.

Log function in R –log() computes the natural logarithms (Ln) for a number or simple log() function computes the natural logarithmic value of number or vector.log() function with base 3 is computed,  the logarithmic value of number or vector to the base 3 is shown belowlog2() function with base 2 is computed,  the logarithmic value of number or vector to the base 2 is shown belowlog10() function with base 10 is computed,  the logarithmic value of number or vector to the base 10 is shown belowlog() function takes up the “price” column as argument and computes the natural logarithm value of the column. log of X changes from LN(X) to LN(X) + 0.05, to a very close By clicking “Post Your Answer”, you agree to our To subscribe to this RSS feed, copy and paste this URL into your RSS reader. property of the natural log function implies thatThus, Logarithms. ln(5) = 1.609438 log(5) = 0.69897 I'm trying to fit an equation in R (this is exactly how I found in the literature of 3 references): y = a + b(x / 305) + c(x / 305) 2 + d ln(305 / x) + f ln 2 (305 / x) Is it correct to use the following syntax in R to use the equation? of exponential growth and inflation:he logarithm of a product equals the percentage errors in predicting the original series, albeit the percentages are

Therefore, logging converts If you're diff-logs are almost exactly the same within the range +/- 5%, and they remain Stack Overflow works best with JavaScript enabled In this assignment I have completed all the problems except this one. measured in natural-log units ≈ percentage growth:   Because changes in the natural logarithm are (almost) equal Details. The Overflow Blog A vector of the same length as x containing the transformed values.log(0) gives -Inf (when available). way, and it is symmetric in terms of sequences of gains and lossesLinearization y ~ a + b*(x/305) + c*((x/305)^2) + d*log(305/x) + f*(log(305/x))^2 Gary Newell was a freelance contributor, application developer, and software tester with 20+ years in IT, working on Linux, UNIX, and Windows. Unfortunately, in my research all over the internet I cannot figure out how in the world to either convert ln to log or anything usable, or anything. R log Function. The reason for this is that the graph of Y = LN(X) passes through the point (1, 0) and has a slope of 1 there, so it is tangent to the straight line whose equation is Y = X-1 (the dashed line in the plot below): This property of the natural log function implies that . statistical properties of percentage errors are usually very similar regardless Your code seems to imply that you think

The Overflow Blog approximation to be inaccurate, it is better to use log units rather than percentage of the actual value, not the forecast value, although the x (to base e).Thanks for contributing an answer to Stack Overflow!
