Problems in using the specific effect significance function in multiple mediating constructs about seminr

[soumyaray]

Hi @samirnemechaves I can help you look into this. But before fully investigating why you are getting a "NaN" result, I want to point out that even after one mediation the indirect effect is -0.001. After two or three more mediations, it will be likely around 0.00001 or smaller – that effect is essentially zero. One suspicion is that your mediated effect is so close to zero that that trying to compute a T statistic (note the SD is also tiny) is getting close to a division by zero, causing the error. You can see if this is the case by progressively adding one more mediator at a time to the specific_effect_significance function. I think it is safe to simply say the four-times mediation is producing nearly a zero effect and so there can be no hope of anything remotely significant.

Let me know if you want me to pursue it further: it will help if can email me (email in my profile info) your data so I can confirm things on your code+data combination. I will ensure to delete your data as soon as this issue is resolved.

Thank you very much for your help, I understand what you mean, I had not thought about it that way and that is probably the reason, of course, I will send you the email with what you requested

Again, thank you very much
