For the statistic t, with ν degrees of freedom, A(t | ν) is the probability that t would be less than the observed value if the two means were the same (provided that the smaller mean is subtracted from the larger, so that t ≥ 0). It can be easily calculated from the cumulative distribution function F ν (t) of the t distribution:
From the t-test, the difference between the group means is 6-2=4. From the regression, the slope is also 4 indicating that a 1-unit change in drug dose (from 0 to 1) gives a 4-unit change in mean word recall (from 2 to 6). The t-test p-value for the difference in means, and the regression p-value for the slope, are both 0.00805. The methods ...
In statistics, the Glejser test for heteroscedasticity, developed in 1969 by Herbert Glejser, regresses the residuals on the explanatory variable that is thought to be related to the heteroscedastic variance. [1]
The phrase "T distribution" may refer to Student's t-distribution in univariate probability theory, Hotelling's T-square distribution in multivariate statistics.
In statistics, the matrix t-distribution (or matrix variate t-distribution) is the generalization of the multivariate t-distribution from vectors to matrices. [1] [2]The matrix t-distribution shares the same relationship with the multivariate t-distribution that the matrix normal distribution shares with the multivariate normal distribution: If the matrix has only one row, or only one column ...
Wayang beber (Javanese: ꦮꦪꦁꦧꦺꦧꦺꦂ, romanized: wayang bèbèr (in the ngoko register)) [1] is an Indonesian wayang performance art whose presentation is manifested in a stretch sheets of paper or cloth with pictures in the stylized wayang accompanied by a narration by a dalang. [2]
The proposed LRT system in Jakarta was initially conceived as an alternative to the suspended Jakarta Monorail construction project. The suspension of the monorail project was due to the objection of the Governor of Jakarta, Basuki Tjahaja Purnama, to the construction of the monorail depot above the Setiabudi Reservoir.
In finance, the T-model is a formula that states the returns earned by holders of a company's stock in terms of accounting variables obtainable from its financial statements. [1] The T-model connects fundamentals with investment return, allowing an analyst to make projections of financial performance and turn those projections into a required ...
