Make causal claims about why things happen‚ prevent bad stuff‚ promote good stuff. “experiments" Correlational - descriptive‚ observational. Does not make causal claims. “studies" Variable types (SS Stevens‚ 1946) Nominal - assign item to category; are discrete / categorical Ordinal - rank order items; are categorical‚ but often treated

Now it is possible to define white noise as a stochastic process (which is statistically stationary) defined by a marginal distribution function (V.I.1-1)‚ where all Xt are independent variables (with zero covariances)‚ with a joint normal distribution f(X1‚ X2‚ ...‚ XT)‚ and with variance

values of state variables (xt) such as the worker’s future lifespan‚ health status‚ marital or family status‚ employment status‚ and earnings from employment‚ assets‚ Social Security retirement‚ disability‚ and Medicare payments. Given specific assumptions about workers’ preferences and expectations‚ the model generates a predicted stochastic process for the variables {ct‚dt‚xt}. This paper‚ however‚ focuses on the inverse or "revealed preference" problem: given data on {ct‚dt‚xt}‚ how can one go backward
