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.

- 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).
- linear correlation
- quadratic regression
- polynomial regression
- moving averages
- chi-square for a two-by two table and for an n by m contingency table
- moving averages - with various (e.g. exponential) weighting
- cubic splines (smoothing, not interpolating)
- other types of splines, e.g. 'linear' splines
- erfc-1 inverse error function complement (i.e. tables of integrals of the normal (Gaussian) curve, or mathematical approximations)
- erfc error function complement
- Table of significant values for t test at P < 0.01 one sided or two sided - or polynomial approximation
- Table of significance levels for chi square test
- Table of significance levels for F distribution as arising in ANOVA
- Confidence limits for binomial variables; possibly for multinomial variables

Thanks and Regards

-Asif
