B'L : Legendre's Constant = 1
Sum(1/2i) : 1 + (1/2) + (1/4) + (1/8)... = 2
3 : HTML Character code for "3". &# is a prefix normally given for
these characters, the 'x33' means 33 base 16 (or 51 decimal). Note if you
type "3" into a Reddit comment you get "3" :)
2-1 (mod 7) : In normal modular arithmetic, subtract the "mod" from the
calculation until you get a number less than the "mod". So 15 mod 11 = 4. In
inverse modulo arithmetic, you're asking what number, when multiplied... 阅读全帖 |

I have a question about analyzing longitudinal data.
Say I have repeated meaurements on both dependent(DV) and independent (IV)
variables.
My data in long-format looks like:
Subject time DV IV Cov1 Cov2

我估计他可能是搞反了。而且还写错了（没有WRC，只有WRX）。
All versions of the SVX sold were equipped with automatic transmissions.
Depending on the country, Subaru had two versions of their All-Wheel-Drive
system for the automatic transmission, called ACT-4 or VTD. The first system
, called ACT-4 (Active Torque Split) by Subaru, was the same setup commonly
found on other Subaru models of the period, and used a variable clutch pack
center differential using a 90% / 10% power split front to rear, which could
transfer up t... 阅读全帖 |

如果要交给公司30%，他自己拿到的就是500000X2.5%X（1-33%）X70%。
楼主拿到的就是500，000×2.5％X33％。 |

combining synchrotron ERSF beamline X33 SAXS/CryoSAXS with X-ray
crystallography,

To improve the resolution and cross-validate structural models.
Small-angle X-ray scattering (SAXS) reveals low resolution (1-2 nm)
structures of biological macromolecules
in close-to-native solutions for an extremely broad range of sizes from
small peptides to huge
macromolecular machines and at variable conditions.
