Results of fitting 10,000 data sets using eight methods (MEE paper)

Description

Default simulation results from generating 10,000 data sets from a bounded power law, with $x_min=1, $x_max=1000$ and $b=-2$, and fitting each set using the eight methods, as described in MEE paper. Results are used to produce histograms and confidence intervals of estimated exponent $b$ in MEE Figures 3 and 4, and statistics in Table 2 (except for MLEbin method).

Usage

eight.results.default

Format

A list with elements:

• Llin.rep.df: Dataframe with columns slope, confMin and confMax, giving the estimated slope, min and max of 95% confidence intervals from the Llin method, with each row representing the values for one of the 10,000 simulated data sets

• LT.rep.df, LTplus1.rep.df, LBmiz.rep.df, LBbiom.rep.df, LBNbiom.rep.df, LCD.rep.df: Corresponding respective data frames for the next six methods

• MLE.rep.df: Corresponding dataframe for the MLE method but with the first column estimating $b$ not a slope

• MLEfix.rep.df: Same as MLE.rep.df but for the MLEfix method, fixing $x_max$ to the known value of 1000 for each simulated data set (for Figures A.3, A.4 and A.5 of MEE).

• MLE.rep.xmax: The corresponding estimate of $x_max$ for the MLE method (namely max(x)) for each simulated data set.

• b: Default value of b (namely -2) for simulations.

• xmin: Default value of xmin (namely 1) for simulations.

• xmax: Default value of xmax (namely 1000) for simulations.
