|
| These different models for covariance function with some modifications can be incorporated into our mapping strategy. |

| The residual covariance matrix of the share equations will be singular, and thus one equation must be omitted when estimating the system. |
|
| Each eigenvector of the observational error covariance matrix is multiplied with a random number. |
|
| Logistic regression was used instead of univariate chi-squares so that covariance among the variables would be taken into account in the analyses. |
|
| One-way analysis of covariance, with pretest scores as covariants, were used when tests for homogeneity of variance dictated that ANCOVA was warranted. |
|
| The power received by a polarimetric radar can be expressed by the covariance, coherence or the backscatter Kennaugh matrices. |
|
| A covariance matrix is a mathematical concept that measures how several asset prices move together over time. |
|
|
|
| The initial covariance matrices of each lander were set to correspond to a 15 by 8 kilometer landing ellipse with a semimajor axis in the East-West direction. |
|
| They show that increased disclosure also reduces the covariance between firms' cash flow estimates as part of non-diversifiable risk. |
|
| The technique is intended to integrate Mendelian transmission genetics, allelic frequency, and penetrance with the patterns of covariance expected in polygenic inheritance. |
|
| As a consequence, in much of the oceanic waters dissolved inorganic phosphorus and nitrogen exhibit a close covariance. |
|
| To understand this, central bankers need a model of the time-varying covariance matrix of asset returns. |
|
| Once aggregated, the data can be combined to construct estimates of the daily conditional covariance matrix. |
|
| Compared to the scattering matrix, the covariance matrix is a means of expressing the properties of the received signal in the power domain. |
|
| To keep the state covariance matrices realistic, the Filter includes the effects of both systematic errors and plant noise. |
|
| In other words, the covariance matrix relates the power of the scattered EM wave to the power of the incident wave. |
|
| As a consequence, covariance matrices of the coordinate data are not of full rank, and the degrees of freedom for some statistical tests need to be adjusted. |
|
| To compare the sites, plant age, A, was transformed as log to linearize the relationships, and log was used as the covariate in covariance analysis. |
|
| Because the components must sum to unity, converting values to proportions produces a linear constraint, which causes the sample covariance matrix to be singular. |
|
| We then used the analysis of covariance to test for differences between the slopes of the regression lines for the eubacterial and the archaeal data sets. |
|
| We apply the model to the covariance matrix of size-sorted stock returns and find that two factors are sufficient to capture most of the dynamics. |
|
| A number of possible sets of variables from the academic finance literature are then examined to see how well they forecast the covariance matrix. |
|
| The denominator of the weight is the same as for the New-York geopotential increment but the numerator is different and is the background-error covariance between the wind in Montréal and the geopotential in New-York. |
|
| The model predicts that for a given level of covariance risk, the asset must generate an expected return of a certain amount in excess of the risk-free rate in order for the asset to be willingly held by investors. |
|
| If the general covariance of equations is indispensable and unambiguous, then what could be the limiting transition to classical equations, which are not generally covariant? |
|
| The unequal impacts of policy on aggregate inequality are largely offset by the negative covariance of policy impacts and original income, as discussed in our November report. |
|
| Portfolio managers use the covariance matrix in designing tracking strategies where the return on their portfolio is designed to closely follow the return on a benchmark portfolio. |
|
|
|
| In most cases, this requires estimates of the standard error of the estimates and, if the estimates are not independent, an estimate of the covariance between the two estimates. |
|
| The DATA matrix is then decomposed using Singular Value Decomposition, which yields the eigenvectors of the covariance matrix. |
|
| Cov is the covariance between direct additive genetic and maternal effects. |
|
| We used the bootstrap covariance matrix for the means and medians of moral hazards to perform Wald tests for equality. |
|
| Follow-up scores for each measure were examined using an analysis of covariance with the prescore values as covariate. |
|
| Several major studies using a political culture approach appeared simultaneously with the behavioral studies of the late 1950s, adding psychological and anthropological insights to statistical covariance. |
|
| The most common measure of variability is variance and the corresponding measure of correlation between two variables is covariance. |
|
| The validity of the vanity scale was assessed using covariance structure analysis of the data. |
|
| In addition to the filter's covariance matrix, the calculation now takes into account the correction vector for each measurement, and the processing indicator for the latest measurements. |
|
| The general theory of relativity was intended to be a generally covariant account of spacetime, and its general covariance was intended to express the general relativity of motion. |
|

|
| A two-factor multivariate analysis of covariance was used to evaluate the effects of temperature and growth on metamorphic date and metamorphic mass. |
|
| That is, the observed covariance between indicator y1 and y3 would mirror the understandable causal behavior of the corresponding underlying latents. |
