Dear All: I have two time series with N time points each. Each time point is covered by L independent measurements. Which test should I use to test for difference between these time series? Is there
Dear All: I need your urgent advise. My lab asked me to provide the specification of absolutely the best desktop computer currently available on the market, which would be able to do the fastest S+6
Dear All: I have a simple problem with character variables. Suppose that I have a long string of characters, say x<-"0010012303456020017854665890641431456880010291237641500107845312331" and a shorter
Dear All: I am trying to make use of argument "restart" in the ordinary differential equations solver "ivp.ab". I need to output trajectories, i.e., solutions of the system of ODEs at the sequence of
Dear All: This question should be probably addressed to the Insightful people, but maybe somebody else can elucidate the issue. In the S-PLUS 2000, it was very easy to import an Excel file using GUI.
Dear All: I am analyzing a time course microarray experiment. I have only 6 chips taken in the moments of time 1,2, 10, 50, 85, 100 (relative units). I am thinking to apply time series analysis metho
Many thanks to Spenser Graves, Eric Zivot and Zhu Wang for help regarding my request "AR for short, unequally spaced TS" Kalman filtering seems to be the only reasonable approach in my case. Zhu Wang
Dear All: I have encountered a problem I have never seen before ( I am S+ user since early 90s). I am conducting a big computation where I create the permutation distribution of euclidean distances b
Dear All: I would appreciate an advice on the following matter. I have a data set organized as a matrix with 20000 rows and 72 columns. The column names represent a chierarchical structure. Namely, t
Many thanks to Andy Liaw, Richard Heiberger and Tim Hesterberg for prompt response regarding my request on 2D->4D transformation. Now I am thinking about an inverse procedure: Transforming 4D array t
