Hi, is there an easy way to get the calculated weights in a regression equation? for e.g. if my model has 2 variables 1 and 2 with coefficient .05 and .6 how can I get the computed values for a test dataset for each coefficient? data var1,var2 10,100 so I want to get .5, 60 back in a vector. This is a one row example but I would want to get a matrix of multiplied out coefficients

Hi, I have some queries that I use to get time series information for 8 seperate queries which deal with a different set of time series each. I take my queries run them and save the output as csv file and them format the data into graphs in excel. I wanted to know if there is an elegant and clean way to read in 1 csv file but to read the seperate matrices on different rows into seperate

Hi, 1) I have noticed that when I use the aggregate function it outputs numbers in the results. for example: aggregate by product group.1 Aggregate 1 ProductA 1000400.00 2 ProductB 23232323.00 3 Missing 232323.00 is there a way to suppress the numbers infront of aggregate outputs. I checked and they don't look like columns when I do a summary so I can't -1

Hi, I see the following is the credit scoreing in R guide : m2<-glm(formula = good_bad ~ checking + duration + history+ purpose +amount + savings + employed + installp + marital + coapp +age + other + depends + telephon + foreign +checking:amount What does checking:amount mean? Regards, Xiaobo Gu
