How to find your dress shirt collar size
Run a tape measure around the base of the neck, right where the collar rests, then add 1 cm of comfort. On a formal shirt the numeric size matches the neck circumference in centimeters, so a 38 means a 38 cm neck. The Brazilian letter-to-numeric chart goes P = 37/38, M = 39/40, G = 41/42, GG = 43/44. So a 40 cm neck takes a 40, which is an M. Go below your actual neck measure and the shirt chokes you. Go more than 2 cm over and the collar gaps around the Adam's apple.
Applications
Bespoke tailoring and made-to-measure shirts. Executive and corporate uniforms. Online orders from Brazilian retailers such as Riachuelo, Hering, Renner, or formal labels like Aramis and Individual, where a wrong-size return costs you. And fittings for wedding suits and groomsmen.
FAQ
Slim fit changes the collar number? No. The collar still follows your neck measure. Slim fit only takes in the torso and the sleeves.
Should I measure over the shirt collar? No. Put the tape right against the skin at the base of the neck. Any fabric in the way throws the number off.
Between two sizes, which to pick? Size up. A tight collar nags at you all day, while a touch of slack hides easily under the tie.

CIR Bond Price (Cox-Ingersoll-Ross)
Computes the price of a zero-coupon bond with the Cox-Ingersoll-Ross model, the successor to Vasicek that fixes its biggest flaw: CIR prevents negative interest rates, because the volatility shrinks as the rate approaches zero. It also has mean reversion and yields an affine closed form for the bond price. It's one of the most used short-rate models in practice. Enter the reversion speed, the long-run mean, the volatility, the current rate and the maturity.
Cliff's Delta (Effect Size)
Computes Cliff's delta, a non-parametric effect-size measure between two groups. It answers a direct question: if I draw a value at random from each group, how much more likely is one to be larger than the other? It ranges from −1 to +1; zero means complete overlap. Because it works only with order comparisons, it requires no assumptions about the distribution and is robust to outliers. It's the ideal companion to the Mann-Whitney test. Enter the two groups of values.
