Hello Gretl Enthusiasts!

I hope this message finds you well. I am reaching out to this knowledgeable community as I embark on a unique project that involves utilizing Gretl for the estimation of environmental and engineering parameters. While I've already dived into Gretl for this purpose, the project's diversity from traditional econometrics poses a few challenges.

Specifically, I am looking to run regression models where I can create custom formulas and expressions. To give you a glimpse, my requirements involve working with a Cartesian coordinate system, something like y = a + d(sine(b)), as I heavily rely on spatial data in my study and also structural health.

I could also use TLS and GLS models - can I run them in gretl and if so where can I find examples of implementations?

Later we will attach soil, air, temperature, rain etc to the model but these will follow a linear model approach easily.

As a newcomer to Gretl, I am seeking honest assistance, guidance, and insights from the experienced members of this group. If anyone could spare a moment to share your expertise, provide script help, or guide me on using the GUI to achieve these objectives, I would greatly appreciate it.

Your support will not only contribute significantly to the success of my project but will also help me enhance my understanding of Gretl in a practical context. I am eager to learn and absorb insights from the Gretl community.

Thank you in advance for your time and assistance. I look forward to the valuable input from this esteemed group.

Best regards,

Tony Aspiring Gretl Enthusiast
