Excel

Making Histogram in Excel - Just Paste (en_paste_histogram.xls)
  • Just paste your data in the Excel.
  • You can choose maximum, minimum, and interval count in the histogram.
  • The output graphs are [Original samples], [Frequency Histogram], [Share Histogram], and [Cumulative Distribution]
  • The maximum value of sample size is 65518. The maximum value of interval count is 100.
Simulation of Ratio between Averages (en_average_ratio.xls)

Visual Statistics and Econometrics by Monte Carlo

  • Random numbers are regenerated with holding down [F9].
Unbiased Variance Estimate (en_variance.xls)
  • Dividing sum of squared deviation by (n-1) gives unbiased variance.
Central Limit Theorem and Pseudo-normal Random Number (en_clt_normal.xls)
  • This file shows central limit theorem and an idea of statistical test.
Regression: Analysis Toolpak Style (en_ols_data.xls)
  • This file shows behavior of regression results in each setting.

Stata

Visual Statistics and Econometrics by Monte Carlo

  • I write important comments in both Japanese and English.
  • We can assign arbitrary values in Input Part.
  • These files show the degree of bias and accuracy in each setting.
Modification of Attenuation Bias (con_mod_attenuation.do)
> [Sample Output]
  • Confirmation and modification of bias by measurement error of regressor.
Estimator Distributions of OLS and IV (ols_iv_dist.do)
> [Sample Output-1] [Sample output-2]
  • Estimator distributions of OLS and IV with given correlation [error and regressor] and [regressor and IV]
  • This file shows the risk of weak IV. For reference, Staiger and Stock(1997),
Selection Bias and Heckit (selection_heckit.do)
> [Sample Output]
  • Sample selection(e.g. self-selection) bias and Heckit.

Versatile do-file

  • I write important comments in both Japanese and English.
  • These do-files are self-running by making sample.
Calculation in Each Group (calc_each_group.do)
  • Calculation of arithmetic mean, geometric mean, and cumulative value in each group.
Two-stage Summary Table (two_summarize.do)
  • Summary table by two-dimensional group.
  • The output statistics are [non-missing, mean, s.d., min, percentile1-percentile99, max],
Ranking (ranking.do)
  • If three IDs get the highest points, the ranking of the second highest points is 4.
F test by Coefficient of Determination (Ftest_R2.do)
  • If we use many fixed effects, this might be useful.
Histogram and Export (histogram_out.do)
  • Though Stata has "histogram" command, this might be useful to export the histogram.
Correlation Matrix by ID and Round (corrlationM.do)
  • Correlation matrix and meeting count by each i and j.

MATLAB

Loading CSV: The first row contains the vector names (load_ncsv_en.m)
  • This script loads CSV using the first row as the variable name. (e.g. sample_co.txt)
  • If your data is Excel, insert the variable names in the first row and save as CSV in advance.
  • This script can load space-delimited (e.g. sample_sp.txt). In that case, delete the line head % in [% Data= dlmread(char(Datafile),' ',1,0);].
  • You'll be able to load mat-format with one line after you save once.
