Is it possible to do meta-regression with GAMLSS? I am about to conduct a meta-regression analysis to fit some age-related changes. Since the GAMLSS approach is highly suggested in the normal regression of such data, I want to apply GAMLSS to my study. However, I could not find avalible packages to achieve this. Could any one help me? If indeed there's no available packages, is there any way to achieve that easily? I cannot simply apply the meta-regression with the normal GAMLSS method, since the latter does not take the variance of studies into account. Any suggestions are appreciated.

There is a meta-analysis example using gamlss on
pages 341-345 (in the Chapter 10: Random effects) of
