the night before…
… my Statistics exam and I have come up with some final notes -
- I can’t remember things that aren’t personally meaningful (i.e. the stuff I don’t get).
- I don’t get statistics.
- Therefore, I will not be able to rote learn Advanced Statistics in a one-night-cramming session.
If I am to undertake this exam I cannot be sober.
- If I am not sober I am either drunk or hungover.
- I will not be drunk because the exam is at 9 am and I haven’t gotten that bad yet.
- Therefore, I will be hungover.
You can imagine the state I am in.
On the upside- haven’t I just nailed formal logic!?
Miracles can happen, right? All those assumptions tests for outliers must mean they exist. Or are they just errors in measurement?
Last glass - here’s to unsystematic variance, the imperfect theory of psychometrics, its continued misuse and misinterpretation and the other unmeasurable f-test, faith.
Risk Adjusted Life Expectancy
Please note that the life expectancy adjustment is an estimate only and provided without confidence intervals.
The effects are also univariate and the interactions between the factors are not taken into account.
Base Life Expectancy: 82.39 years
Risk Factor Adjustment: 5.4 years
Risk Adjusted Life Expectancy: 87.79 years

So does the regular drinking account for the extra years? Although ‘moderate exercise’ is a somewhat generous (if not earnestly aspiration-al) estimation of my physical activity.
Life expectancy calculations are probably not the most conducive activity for getting to sleep… Maybe I should get a TV? I heard Aldi is selling a big, fat cheap one… Does TV viewing correlate with higher or lower longevity? I bet it is significantly correlated to somnolence.
