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
