.step param name function1 function2 function3 where function1 is the first value, function2 is the last value and function3 is the increment. More over all variables used in the functions have been defined respective .param commands.

Thank you KSKelvin. Based on this I was able to simulate the following resistive divider circuit.
Is there a way to extract the worst-case Min and Max Vout variation by using some variation of the “.meas” command applied to Vout?

You can consider Monte Carlo method for this type of analysis. This setup sweep 2000 times per temperature point, therefore, total 6000 run with simulation time about 3 mins.
