In my opinion, it's a good strategy to transform your data before performing linear regression model as your data show good log relation: > #generating the data > n=500 > x <- 1:n > set.seed (10) > y <- 1*log (x)-6+rnorm (n) > > #plot the data > plot (y~x) > > #fit log model > fit <- lm (y~log (x)) > … WitrynaFor fitting these estimates to data, consider measuring the goodness of fit for discriminating between two solutions when they are available. A $\chi^2$ statistic should do fine. This approach is illustrated in the following R code, which simulates data, performs the analysis, draws a histogram of the data, and overplots the solutions. …

Witryna1 wrz 2015 · Sorted by: 2. The simplest way to see this is by taking. lim x → ∞ d d x ln x = lim x → ∞ 1 / x = 0. and as such observing that because the slope approaches zero ln x flattens out as x → ∞. Unfortunately, this method offers zero intuition. Similar behavior occurs in a discrete case with the harmonic series. オペラシティ 何階Witryna17 sty 2024 · 1 Answer.
