I ran a model with 3 chains and I obtained the following acceptance rates:
Chain 1: 6.8844%
Chain 2: 17.4192%
Chain 3: 28.5928%
Which one should I choose in order to play with mh_scale ?
I mean, if the acceptance rate of the last chain is comprised between 0.33 and 0.25, is it sufficient to conclude that we obtained satisfying acceptance rates ?
Or should all the 3 chain’s acceptance rates be comprised between 0.33 and 0.25 in order to conclude that we obtained satisfying acceptance rates ?
Thank you for you answer,
