Hi There, As I have learned the hard way, let me discuss my question, idea or feature here before doing actual work on it... distance_of_time_in_words_to_now() seems to be unable to tell if this distance is in the future or in the past. I''d really like to see ''in 5 days'' or ''5 days ago'' depending on, well, if it was 5 days ago or will be in 5

Hi R-users, I would like to find the goodness of fit using Chi-suare test for my data below: xobs=observed data, xtwe=predicted data using tweedie, xgam=predicted data using gamma > xobs <- c(223,46,12,5,7,17) > xtwe <- c(217.33,39,14,18.33,6.67,14.67) > xgam <- c(224.67,37.33,12.33,15.33,5.33,15) > chisq.test(xobs, xtwe = xtwe, rescale.p = TRUE) Error in chisq.test(xobs,

Hi, Does anyone know an instruction to perform a test (or to construct a confidence interval) for the variance of a normal population (distribution). The test statistic is (n-1)*S´^2/sigma^2 and has chi square (n-1) distribution. Thank you, Alexandra [[alternative HTML version deleted]]

Dear R users, I have a data set of 25 cases with 150-160 explanatory variables(the number of which depends on what I choose from 200 odd digitalized spectrum strength numbers) and one dependent variable(a sensory test result). My natural choice is to work on a principal component analysis using the explanatory variables, thus enabling to characterize and describe the data space, and make a

Hi, I hope this is the correct way to announce a new gem: validation_hints https://github.com/acesuares/validation_hints https://rubygems.org/gems/validation_hints It''s purpose is to get a list of ''hints'' derived from validation on a model or attribute. These hints then could be used in the user interface, for instance for displaying a tooltip or other
