5. Street Fighter II, the World Warrier (2021) from fabiensanglard.net
   378 by birdculture 19h ago | | |

   Article: 7 min

   This article discusses an interesting anecdote about Street Fighter II, where Akiman discovered a typo in the subtitle 'World Warrior' just three days before shipping. He had misspelled it as 'World Warrier'. The CPS-1 hardware used for the game could not alter the artwork once burned into the GFX ROM. To fix the mistake, Akiman layered other sprites over the typo to make it look like an 'o', and then replaced some tiles with others from Guile's calves palette to create a dot on top of the 'i' in 'Warrior'. The typo was later fixed in subsequent versions of the game.

10. Why does a least squares fit appear to have a bias when applied to simple data? from stats.stackexchange.com
    239 by azeemba 13h ago | | |

    Article: 3 min

    The article discusses the apparent bias in a least squares fit when applied to correlated data and compares it with the direction of maximum variance obtained from diagonalizing the covariance matrix. The author seeks an intuitive explanation for why the linear fit does not pass through the center of the data cluster.

    The article contributes to the understanding of linear regression and its limitations in handling correlated data, which can inform better model selection and interpretation in various fields such as finance, economics, and social sciences.

    • Diagonalizing the covariance matrix to find the direction of maximum variance provides a different perspective on the data distribution.
    • The fit minimizes vertical distances, breaking symmetry in the system.

    Discussion (62): 16 min

    The discussion revolves around comparing different regression methods (least squares, TLS, Deming) for datasets with varying levels of noise in both x and y variables. Participants debate when to use each method, discuss their advantages and limitations, and explore alternative techniques like PCA and ANOVA. The conversation also touches on the impact of noise on statistical inference and causal relationships.

    • Least squares regression may not be appropriate when both variables have significant noise
    • Total least squares or Deming regression is preferred for datasets with errors in both x and y

    Counterarguments:

    • Least squares is still appropriate when y has more noise than x
    • The choice of regression method depends on the specific characteristics and requirements of the dataset
