what is tau meaning here, thanks.

[liamxg]

tau = 18.4332061932401

[liamxg]

is this normal or not?

[xavierdidelot]

Maybe, it depends what your data looks like. It would be better to plot the effective population size on a log scale, and also to look at the growth rate.

[liamxg]

[liamxg]

plot(fit,logy=TRUE) like this, right?

[liamxg]

[liamxg]

could you please tell me how to look at the growth rate, thanks.

[xavierdidelot]

Yes logy=TRUE is indeed what you need to use to have the y-axis on a log-scale. To plot the growth rate you need to use growth=TRUE It looks like your analysis is completely uninformative.

[liamxg]

thanks for your help, like the following?

plot(fit,logy=TRUE,growth=TRUE) Warning message: In xy.coords(x, y, xlabel, ylabel, log) : 17 y values <= 0 omitted from logarithmic plot

[liamxg]

[xavierdidelot]

plot(fit,logy=FALSE,growth=TRUE) would be better, for the growth rate you usually don't want the logged y axis.

[liamxg]

thanks. like this?

[liamxg]

no 95% interval

[xavierdidelot]

Yes but this looks hard to believe. You should check your data is used correctly. Email me if you need help.

[liamxg]

[xavierdidelot]
