Thank you for spotting this, I now fixed your second issue. However, according to the object size, I do not see why the family object size is an issue. E.g.
R> set.seed(123)
R> n <- 100000
R> x <- runif(n, -3, 3)
R> y <- 10 + sin(x) + rnorm(n, sd = 0.3)
R> b1 <- gamlss2(y ~ s(x), family = BCT)
GAMLSS-RS iteration 8: Global Deviance = 44472.3394 eps = 0.000005
R> b2 <- gamlss2(y ~ s(x), family = BCT, light = TRUE)
Start estimation ...
GAMLSS-RS iteration 8: Global Deviance = 44472.3394 eps = 0.000005
R> format(object.size(b1), units = "Mb")
[1] "62.8 Mb"
R> format(object.size(b1$family), units = "Mb")
[1] "0.7 Mb"
R> format(object.size(b2), units = "Mb")
[1] "3.2 Mb"
R> format(object.size(b2$family), units = "Mb")
[1] "0.7 Mb"
Thanks a lot for addressing the problems quickly.
I don't think it's an issue per se but if you have a large number of models, 20% memory less is a significant amount. Anyway, it's good to post it for whoever will have a similar situation to mine
Dear developers,
last April I made a post about anonymizing the gamlss model and it was suggested to move to gamlss2. The suggestion was good and since I've promised a feedback here it is:
The size of the gamlss2 object with the
light=TRUE
is still to big for exporting several models. To reduce it I set the$family
field to the family name instead of the family object that accounts 1/3 of the object size:Furthermore, I've been consistently getting the following error:
> Error in (function (condition) : node stack overflow
Which seems related to the interaction of the smooth term and a variable. Using
gamlss::pb
,gamlss2::pb
ors()
seems to make no difference. I can't really figure it out how to fix the problem. I found this error with 3 different datasets. What i understood was that "Inter-actions with nonparametric smooth terms are not fully supported, but will not produce errors; they will simply produce the usual parametric interaction" (p.48).**sessionInfo()**
