Statistics

Read probability, risk, and performance without fooling yourself.

Statistics helps readers understand uncertainty, volatility, averages, base rates, backtests, and why good decisions can still have bad outcomes.

Core Topics

Useful statistics for finance, trading, and research.

Probability

Base rates and odds.

Compare a story against historical frequency before treating it as a signal.

Volatility

Range and drawdown.

Understand standard deviation, drawdown, variance, and why average returns can mislead.

Correlation

Relationship is not cause.

Use correlation carefully when comparing Bitcoin, stocks, gold, rates, and currencies.

Backtests

Backtest humility.

Watch for overfitting, small samples, survivorship bias, regime change, and data snooping.

Research note

Statistics can reduce confusion, but it cannot remove uncertainty. Use it to improve questions, not to create false certainty.
