I wonder if there is a package that will estimate a Zero Inflated Poisson Model (ZIP), and also if there is a package that will estimate what is called the Tobit model: that is a combination of censored and observed values in the same sample.

...have a set of data comprising a list of numbers of eggs on mosquito guts that range from 1 to 157. How can I get R to draw a barchart of the distribution of the data (i.e. x axis= number of eggs on a gut, y axis=number of mosquitoes found with that number of eggs)? Data is listed below. Thanks, Georgina Number of eggs on each mosquito gut: [1] 1 1 1 1 4 2 1 12 12 1 2 1 12 6 11 33 33 94 17 [20] 3 14 12 54 1 16 10 7 12 4 7 22 1 34 2 11 34 22 27 [39] 4 1 27 1 1 157 1 7 31 3 6 24 6 7 23 10 54 3 12 [58] 12 5...

Hi! I am trying to work out the code to get a Fibonacci sequence, using the while() loop and only one variable. And I can't figure it out. Fibonacci<-c(1,1) while (max(Fibonacci)<500){ Fibonacci<-c(Fibonacci, (max(Fibonacci) + ?(Fibanacci))) } How can I tell R to take the value one before the max value? (Without defining another variable) (Probably super easy... I am a

I have the attached data set (csv) and I want to run an analysis of variance on the wingsize data (comparing infected vs non-infected) within and between experiments. Can anyone help me with the command I should use? Many thanks Georgina PhD Student Division of Infection and Immunity B5-29, GBRC 120 University Place Glasgow G12 8TA Tel: 0141 330 5650

Can anyone advise a good transformation for this data below to produce a normalised distribution?

...bject in S-plus, the estimated standard errors are different. It may be different estimators of the variance of the residuals? Which one is the default in R, I don't find that too easily in the documentation. Does anybody know? I'll be very grateful if somebody can help in this matter.

Hi! I have a data set of 86 values that are non-normally distributed (counts). The median value is 10. I want to get an estimate of the 95% confidence interval for this median value. I tried to use a one-sample Wiolcoxin test: wilcox.test(Comps,mu=10,conf.int=TRUE) and got the following output: Wilcoxon signed rank test with continuity correction data: Comps V = 2111, p-value = 0.05846
