Bayesian estimation is not happening

Estimation ML/Bayesian estimation

Hello Sir,

I have been working on this program draft since two days but unable to figure it out why bayesian estimation is not happening ? why the Matrox is not positive definite. Std dev of posterior distributions turn out to be NaN.

I am uploading my program and data file here. Please help me in resolving the error.

Thank you
