Hi,

I am new-comer to statistics and R-Project. I would like to know if these features can be attained in R-Project.Please help.

  1. beta 1 and Beta 2, or gamma one and gamma two for skewness and kurtosis, respectively, including standard errors and tests for significance (relative to values for a Gaussian distribution).
  2. linear correlation
  3. quadratic regression
  4. polynomial regression
  5. moving averages
  6. chi-square for a two-by two table and for an n by m contingency table
  7. moving averages - with various (e.g. exponential) weighting
  8. cubic splines (smoothing, not interpolating)
  9. other types of splines, e.g. 'linear' splines
  10. erfc-1 inverse error function complement (i.e. tables of integrals of the normal (Gaussian) curve, or mathematical approximations)
  11. erfc error function complement
  12. Table of significant values for t test at P < 0.01 one sided or two sided - or polynomial approximation
  13. Table of significance levels for chi square test
  14. Table of significance levels for F distribution as arising in ANOVA
  15. Confidence limits for binomial variables; possibly for multinomial variables

Thanks and Regards
-Asif
