Partially specified mathematical objects, ambient parameters, and asymptotic notation

In orthodox first-order logic, variables and expressions are only allowed to take one value at a time; a variable , for instance, is not allowed to equal and simultaneously. We will call such variables completely specified. If one really wants to deal with multiple values of objects simultaneously, one is encouraged to use the language […]

A short note on the startsWith function

The startsWith function comes with base R, and determines whether entries of an input start with a given prefix. (The endsWith function does the same thing but for suffixes.) The following code checks if each of “ant”, “banana” and “balloon” starts with “a”: The second argument (the prefix to check) can also be a vector. […]

Has globalisation ended?

Apart from inflation and war, what grips current economic thought is the apparent failure of what mainstream economics likes to call ‘globalisation’.  What mainstream economics means by globalisation is the expansion of trade and capital flows freely across borders.  In 2000, the IMF identified four basic aspects of globalisation: trade and transactions, capital and investment movements, migration and […]

Fragmented France

The second round of the French presidential election returned the incumbent President Emmanuel Macron to a second term of office.  Macron won with 58.5% of the vote against the opponent, Marine Le Pen of the right-wing nationalist National Rally, who got 41.5%.  Sounds comfortable – but the voter turnout of 72% was the lowest since […]

Fieller’s confidence sets for ratio of two means

Assume you have a sample drawn i.i.d. from some underlying distribution. Let and . Our goal is to estimate the ratio of means and provide a level- confidence set for it, i.e. a set such that . Fieller’s confidence sets are one way to do this. (The earliest reference to Fieller’s work is listed as […]

Asymptotic normality of sample quantiles

Let be i.i.d. random variables with the cumulative distribution function (CDF) . The central limit theorem demonstrates that the sample mean is asymptotically normal (as long as has a finite second moment): where and are the mean and variance of the random variable with CDF . It turns out that for any , the th […]
