  2. Academic grading in Singapore - Wikipedia

    en.wikipedia.org/wiki/Academic_grading_in_Singapore

    Students with a minimum cumulative GPA of 3.5 (NITEC) or 2.0 (Higher NITEC; 2.5 from 2027), including up to 0.2 bonus points for Co-curricular activity (CCA) and/or 0.1 point for passing Bridging Mathematics, was also taken into consideration for matriculation in polytechnics, though this applies to most diplomas; Higher NITEC students who have ...

  3. Iris flower data set - Wikipedia

    en.wikipedia.org/wiki/Iris_flower_data_set

    Scatterplot of the data set. The Iris flower data set or Fisher's Iris data set is a multivariate data set used and made famous by the British statistician and biologist Ronald Fisher in his 1936 paper The use of multiple measurements in taxonomic problems as an example of linear discriminant analysis. [1]

  4. Exponential integral - Wikipedia

    en.wikipedia.org/wiki/Exponential_integral

    Plot of the exponential integral function E n(z) with n=2 in the complex plane from -2-2i to 2+2i with colors created with Mathematica 13.1 function ComplexPlot3D

  5. Constant-recursive sequence - Wikipedia

    en.wikipedia.org/wiki/Constant-recursive_sequence

    The sequence 2, 1, 3, 4, 7, 11, ... of Lucas numbers satisfies the same recurrence as the Fibonacci sequence but with initial conditions = and =. More generally, every Lucas sequence is constant-recursive of order 2.

  6. Expected value - Wikipedia

    en.wikipedia.org/wiki/Expected_value

    The expectation of X is defined as [12] ⁡ [] = + + +. Since the probabilities must satisfy p 1 + ⋅⋅⋅ + p k = 1 , it is natural to interpret E[ X ] as a weighted average of the x i values, with weights given by their probabilities p i .

  7. Long division - Wikipedia

    So 1 and 12 are less than 37, but 126 is greater. Next, the greatest multiple of 37 less than or equal to 126 is computed. So 3 × 37 = 111 < 126, but 4 × 37 > 126. The multiple 111 is written underneath the 126 and the 3 is written on the top where the solution will appear: 3 37)1260257 111

  8. Exponential distribution - Wikipedia

    en.wikipedia.org/wiki/Exponential_distribution

    In probability theory and statistics, the exponential distribution or negative exponential distribution is the probability distribution of the distance between events in a Poisson point process, i.e., a process in which events occur continuously and independently at a constant average rate; the distance parameter could be any meaningful mono-dimensional measure of the process, such as time ...

  9. Laplace distribution - Wikipedia

    en.wikipedia.org/wiki/Laplace_distribution

    In probability theory and statistics, the Laplace distribution is a continuous probability distribution named after Pierre-Simon Laplace.It is also sometimes called the double exponential distribution, because it can be thought of as two exponential distributions (with an additional location parameter) spliced together along the abscissa, although the term is also sometimes used to refer to ...
