It’s why i read HN through rss. My rss app lets me filter based on keywords in the subject, so i can filter out the nth post about the incremental updates to commonly used models. If i don’t have control over the feed, i cant read this site.
Does anyone have tips for how to use space repetition to be a better knowledge worker? I feel like i could use it to have a better memory of business processes, but i dont know how to get started.
You first have to convince me that it makes sense to (1) do any adjustment in the first place, the adjustments are not reality, and (2) that the chosen adjustment method is the correct one.
To calculate a p-value (roughly spoken), you need to start with a single hypothesis. Then you gather data and the p-value gives you the probability that your data occurs while your hypothesis is false. When you start with a finite set of multiple hypotheses, you need to take that in to account when calculating your p-value.
When you start with data and come up with a hypothesis afterwards, you would have to find the whole potential space of all hypotheses. So, for example, how many hospitals are there? Do you only consider US? Do you only consider nurses or other employees as well? What about only four nurses would that have made it to the news? What about other forms of cancer? What about time? Do you consider the time period of the last 50 years? As you think about what might have made the news, the set of hypotheses grows bigger and bigger and as it approaches infinity, the p-value for any data would approach one. Because when you have a very large set of unlikely hypotheses, the probability that your data accidentally supports one of them is quite large.
P values are common in science for those that don’t know. It measures what the odds are something you observe would happen in just a random sample. Or something like that.
