Quantiles in RThe Guerrilla rules of thumb follow from the assumption that the underlying statistics are exponentially distributed. Hourly rates and units per hour are based on field experience and industry rules of thumb. Some other small sample rules of thumb like the “flip flop” test and “shortfall less than 1” rule were also considered, but didn't seem to be given substantial weight. Another standard hard science method is statistical inference. Several responses; I posit that what's going on with this wage spread is two statistical rules of thumb. Despite decades of careful data collection and mathematical and statistical research, on many large questions we have little more than rules of thumb. They also claim that statistics based systems are more accurate. -The first is that while real women may have curves, women's statistical curves are tighter than men's. Patch leaving behavior is determined by a stochastic dynamic programming (SDP) model, while allowing parasitoids to make mistakes in their estimation of host density when arriving in a patch We use Cox's proportional hazards models to obtain statistical rules of thumb from the simulated behavior. He noticed that his average 800m Burfoot doesn't seem to have done any statistical analysis, or even any research other than asking a few running buddies about their workouts and marathon times. For independent means, error bars representing 95% confidence intervals can overlap and still be statistically significant at the 5% level. While reading Bart Yasso's My Life on the Run, I came across his predictor for marathon times, "Yasso 800s." Yasso was in the habit of doing a 10 x 800m track workout; his rest in between each item was a 400m jog. Simple behavioral rules, or “rules of thumb,” which lead to behavior that closely approximates an optimal strategy, have generated a lot of recent interest in the field of foraging behavior. Companies advocating the statistics system hold that editorially maintained rule bases take a lot of up-front investment and higher costs overall.

On the other hand, statistics based systems require a then the cost of thesaurus creation needs to be added. The exponential PDF and corresponding exponential CDF are shown in Fig.
