  1. Wenn jetzt jemand denkt, dass der #Grossbatteriespeicher am #IRT bei #Föhren dazu dient, den Strom des angrenzenden #Solarpark|s zu speichern, hat sich nach den Fachleuten der #noafd wohl getäuscht. #Erneuerbare können nämlich nicht gespeichert werden. 🤡😅

  6. @guyjantic If you have not only one, but multiple questions, several item response models extend this logic by assuming a latent continuous variable:
    they evaluate whether the responses to the questions can be reconstructed as ordered responses - and ordered in this case meaning 'with reference to this latent variable' (e.g., does being more in favour of rights for pregnant people consistently align with choosing higher categories in the individual question responses).

    Thinking about scale reliability lately.

    An obvious thing to remember is that scale reliability (omega) is the upper bound of correlations it can meaningfully (!) have with anything else.

    This is highly practical, because, in theory (I haven’t fleshed this out yet), this enables us to test construct validity pretty well by attenuating correlations with reliability. This has been done before, albeit (imho) slightly clumsily by Kristof (1983). They used a Spearman Brown approach based on an ideal correlation to establish thresholds a correlation must test against to conclude discriminant or convergent validity. The formula was threshold = rho_ideal * sqrt(rel_a * rel_b). This is less than ideal, because what an ideal correlation is is up to the researcher.

    However, keeping the above fact in mind, we can do better. Kill thresholds and just make it a measure of relatedness altogether that is capped by the lower reliability.

    Let’s call this Kappa = rho_real/sqrt(rel_a*rel_b).

    This should (again, I haven’t tested this yet) give you two types of information right away:
    1)If its >1, then your scale is off.
    2)If it’s less than 1 it informs about construct validity. If it’s less than 0.5, probably discriminant, if it’s higher probably convergent. The extreme the score, the higher the confidence.

    Please correct me If I'm doing some goofing here.

    Please welcome the new #publicTransport system.

    This obviously is not a train and misses the extreme savings from steel #railway #train technics. But it's a giant step forward in the thinking about how to handle and speed up city traffic by public mass transport.

    The top 1/4 of most intelligent chinese are more than the entire population of the US.

    In the end maybe they might save us all ..

  26. On 6 September 2023, there was signing ceremony for #MoU between #Iskandar Regional Development Authority (#IRDA) & Korea Railroad Research Institute (#KRRI).

    The MoU is to carry out Proof of Concept (#POC) for Traffic Signal Prioritization System (#TSPS) related to the Iskandar Rapid Transit (#IRT) project.

    The POC will help IRT in terms of efficient operation & smooth traffic along the #Tebrau IRT Main Trunk at Jalan Tebrau when it is implemented soon.
