I have a set of data, the production of oil from a well. And an equation to predict that forecast.
The equation requires 5 input variables which are real numbers with upper and lower bounds, 1 input variable which must be an integer and 1 input variable which can be 1 of 2 string variables. What is the best optimization routine (I am using nlminb) to use in R to determine the best set of inputs and how to I handle the integer and string inputs when optimizing? I have attached a plot of what I am trying to accomplish as well as my sample code. Thanks, Ryan
