Error when trying to mimic example of simple decline curve

[RAMDHAN ARI WIBAWA]

I got error when trying to mimic example of decline curve from this link :

Simple Decline Curve Analysis Data Function for TIBCO Spotfire | TIBCO Community

an error as follow :

TIBCO Enterprise Runtime for R returned an error (6)

The data function 'DCA_fit (Untitled_Copy)' could not be executed.

Error in optim(par = x0, fn = residfun, x.days = x.days, y.prod = y.p : Function cannot be evaluated at initial parameters

eval(script, envir = .GlobalEnv)

eval(script, envir = .GlobalEnv)

withCallingHandlers({

optim(par = x0, fn = residfun, x.days = x.days, y.prod = y.prod)

when you say mimic, can you elaborate on what steps you followed

I followed the steps here :

 

(2) Hyperbolic Decline Curve in Spotfire - YouTube

 

I used my own dataset and followed the data structure and type as shown by the video tutorial.

 

thank you

It is likely related to the specific input dataset, which I understand is not something you would want to share publicly. I recommend that you open a support case for this in the TIBCO Support Portal (https://support.tibco.com), and the support team will assist you with further troubleshooting. Please include your analysis in the support ticket.
