Dear all, I want to check whether 5 decimal data is 1:1:1:1:1. For example, data = c(14.3,16.2,14.7,18.7,14.5) Since chisq.test() can do the goodness-of-fit test, it becomes my choice. However, I find in the "?chisq.test" help file that it requires "non-negative integers"! It seems that it is inappropriate to do the test using this function. The function requires "integer". But what if we input some decimals as mentioned above? Actually I did it and it seems goes well. > data = c(14.3,16.2,14.7,18.7,14.5) > chisq.test(data) Chi-squared test for given probabilities data: data X-squared = 0.8704, df = 4, p-value = 0.9288 Is this result reliable? Thanks! Dejian
