1. This has to be further divided by the standard deviation to get unit variance.
2. The in the exponent ensures that the distribution has unit variance ( and therefore also unit standard deviation ).
3. Moreover, if the variables have unit variance, for example if they are standardized, then this simplifies to
4. The ?in the exponent ensures that the distribution has unit variance ( and therefore also unit standard deviation ).
5. This yields a one-parameter leptokurtic family with zero mean, unit variance, zero skewness, and arbitrary non-negative excess kurtosis.
6. It's difficult to find unit variance in a sentence. 用unit variance造句挺難的
7. Driving these filters with independent, unit variance, band-limited white noise yields outputs with power spectral densities that match the spectra of the velocity components of the Dryden model.
8. Another characterisation of a Wiener process is the Definite integral ( from zero to time t ) of a zero mean, unit variance, delta correlated ( " white " ) Gaussian process.
9. Driving these filters with independent, unit variance, band-limited white noise yields outputs with power spectral densities that approximate the power spectral densities of the velocity components of the von K醨m醤 model.
10. The hyperbolic secant distribution shares many properties with the standard normal distribution : it is symmetric with unit variance and zero leptokurtic; that is, it has a more acute peak near its mean, and heavier tails, compared with the standard normal distribution.
11. When time and resources limit the number of experimental units, and unit effects cannot be eliminated statistically by testing over the unit variance, it is important to use other sources of information to evaluate the degree to which an F-ratio is confounded by unit effects.
12. One way of making the PCA less arbitrary is to use variables scaled so as to have unit variance, by standardizing the data and hence use the autocorrelation matrix instead of the autocovariance matrix as a basis for PCA . However, this compresses ( or expands ) the fluctuations in all dimensions of the signal space to unit variance.

However, this compresses ( or expands ) the fluctuations in all dimensions of the signal space to unit variance.
14. The gusts generated by the Dryden model are not white noise processes and therefore may be referred to as linear time invariant system with a white noise input that has unit variance, transfer function " G " ( " s " ), and output " y " ( " t " ).
15. where " J " n is the test statistic, " s " 2 is the variance of the sample, " m " is the mean of the sample and " n " is the sample size . " J " n is asymptotically normally distributed with a zero mean and unit variance.
