what is the relationship between observations and models how to calculate observed points of a model nan vs model in data what is the difference between observation and a model of a data set? what is the difference between an observation and a model? if two observations are modeled the model is the best what is observed in n-dimensional data what is observed mean in math how do you find na in a data tally what is the difference between a observation and a model? how many parameters do nn and nb represent which is true about observations vs models? what is the difference between model and observation what is model na vs observation what is the relationship between model and observation why is the value of $na and nb in models important? what is the difference between observer and model what is the difference between observations and models? which is more important observation or model of model what is the relationship between observed and model
