Dear gretl developers, Here is a short (well, maybe not that short) wish list of improvements for gretl that I hope can be implemented: 1. For the genr command, add a function for computing the factorial, i.e. n! 2. For Tools > Statistical tables: Add tabs for (a) Poisson distribution (b) binomial distribution 3. In Tools > Test statistic calculator: Add (a) the possibility for using continuity correction for the one sample proportion test by checking a check box (b) a new tab for calculating a Z-test for comparing two counts (assuming that the counts are large enough for the normal approximation to the Poisson to apply) (c) a new tab for calculating ANOVA for comparison of K means 4. In Tools > Nonparametric tests: Add new tabs for calculating (a) Friedman’s test (the K sample extension of the sign test) (b) Kruskal-Wallis test (the K sample extension of the Wilcoxon rank sum test) 5. For Tools > Probability distributions: Add (a) a tab for the gamma distribution (b) the possibility to choose the mean and standard deviation of the normal distribution 6. In View > Correlation matrix add a check box for also calculating a covariance matrix 7. For View > Principal components: Add the possibility to plot scree plots by checking a check box 8. For View > Cross tabulation, please (a) add that Fisher's exact test is given as default for 2x2 contingency tables (b) add to the GUI radio buttons for the options --row (display row percentages) or --column (display column percentages), and a check box for the option --zeros (display zero entries) (c) add an option to save the contingency table (without the marginal totals) as a matrix 9. For Add > Random variables (a) Change the GUI to look like the one in Tools > P-value finder, i.e. with tabs for the different distributions and text entry boxes for mean, standard deviation, degrees of freedom, etc (b) add the gamma distribution 10. In File > Export data, add options to export in (a) Gnumeric file format (b) LaTeX format 11. Add an option to save a matrix in LaTeX format 12. In the data window, there are currently three columns: “ID #”, “Variable name” and “Descriptive label”. A new column showing if the variable is to be treated as discrete or not would be useful. I hope you will consider implementing these features Best regards Andreas Karlsson
