Please can someone advise me how I can adjust correlations using bonferroni's correction? I am doing manny correlation tests as part of an investigation of the validity/reliability of a psychometric measure. Help would be so appreciated! Cheers, Louise

...shows FALSE starts to appear when n >= 10. Why the inconsistency? compare <- function (n, k) choose(n,k) == gamma(n+1)/(gamma(k+1)*gamma(n-k+1)) compare(5,2) [1] TRUE compare(10,2) [1] FALSE compare(9,2) [1] TRUE compare(9,3) [1] TRUE #etc. _____________________________________ Paul S.P.

Cryer Time Series Analysis and Its Applications: With R Examples by Robert H. Shumway and Robert H. Shumway Introductory Time Series with R (Use R) by Paul S.P. Cowpertwait and Andrew V.

...in other variables? If so, I don't know how to do this. Or, I need to do an overall test like Little's test of missing completely at random. I have spent ages looking online and at packages and can't find anything. Please help! I don't want to use SPSS!

...ma(6)*gamma(16))) == round(choose(20,5)) [1] TRUE So I presume the problem is related to gamma being a real function. However, I'm still not sure why there's a break from TRUE to FALSE for certain values. Any comments would be appreciated! _____________________________________ Paul S.P.

...icients of the first "fundamental" harmonic that the machine is applying - an, bn "low" values of coefficients of the higher harmonics - some noise ~ NID I used lm() to fit the linear model using the code suggested in "Introductory Time Series with R" by Paul S.P. Cowpertwait (2006 SPRINGER SCIENCE+BUSINESS MEDIA, LLC.). Started with 1st harmonic component and then increased up to 6. Here's the results (6 harmonic components, but results are similar with less harmonics): Call: lm(formula = force.fit ~ s + c) Residuals: Min 1Q Median 3Q...

Hello, I am trying to collect several global measures or statistics for time-series as well as packages of R that can compute them. I have found several of them in papers and books, but the literature is so big i am sure i am missing several of them. skewness kurtosis min max mean SD trend seasonality periodicity chaos (Lyapunov Exponent) / Largest Lyapunov Exponent (i think is the same

Hello, I am totally new in the field of time series analysis and forecasting and R. I read that R is a powerful tool for time series. Could anyone give me navigation what models of time series are availiable in R etc? -- View this message in context: http://r.789695.n4.nabble.com/Time-Series-Analysis-and-Forecasting-tp4646637.html Sent from the R help mailing list archive at Nabble.com.
