Uncertainty propagation
...hus have std error associated to
them: alpha (?da) * WaterHight ^ beta (?db). Is it statistically correct to
sample alpha and beta for each run by picking them from a normal
distribution centered on alpha (resp. beta) with a standard deviation of da
(resp. db) and to perform my statistics (mean and standrad edviation of the
model result) on the model output?
It seems to me that da and db are correlated in some way and by doing what I
entended to, I would overestimate the final error of my model...
My statistical skills are rather weak, is there a way people usually deal
with this kind of problems?

Problem with reproducing log likelihood estimated with ghyp package
...ng to reproduce the
likelihood values, I summed the log(dt(x,v)) values and it worked with some
simulated series but not all.
Is there any obvious flaws with this script?
library("ghyp")
series_1=rt(10000,4)
#simulating 10000 relation of student t variables with df=4
#Which implies a standrad deviation equal to sqrt(2)
series_2=series_1/sqrt(2)*5
#To get student t distributed variabler with standard
#deviation equal to 5 I rescale the first series
#When i check the first series with the ghyp package, the result coincides
with
#the sum of log likelihood calculated with dt(x, df, ncp,...

package lmodel2: p-value RMA fitting?
Hi *,
is there a way to obtain some kind of p-value for a model fitted with RMA
using the lmodel2 package?
I know that p-values are discussed and criticized a lot and as you can image
from my question I'm not
very much of a statistican (only writing my bachelor thesis).
As fare as I understood the confidence interval statistic correctly, a
coefficient is regarded as statistically
significant
