Sentence examples similar to cross basis from inspiring English sources

This analysis employed a cross-basis function that describes a bidimensional association between temperature and number of lag days (Gasparrini et al. 2010).

We extended these models to time-varying DLNMs by including a linear interaction between time and the cross-basis variables.

The cross-basis is specified by the choice of two basis, one for each dimension, among a set of possible options such as splines, polynomials, or step functions.

The simpler lag-basis for DLMs in (1) is a special case of the more complex cross-basis for DLNMs in (2).

These models may be fitted through common regression techniques with the inclusion of cross-basis matrix W in the design matrix.

The definition of identical cross-basis functions in all the locations can be problematic in the presence of substantially different exposure ranges.

The set of v x  ×  v ℓ  = 20 coefficients of the cross-basis variables with associated (co variance matrices, estimated in each region, are then reduced.

This modelling class is based on the definition of a cross-basis, a bi-dimensional space of functions describing the association along the spaces of predictor and lags.

The temperature-mortality relationship is modelled through the same cross-basis used for the full two-stage analysis illustrated later, composed by two B-spline bases.

These models are defined by 16 cross-basis variables obtained by the combination of the exposure response and lag response functions, with 4 df each.

Also, alternative parameterization of the cross-basis functions may reduce the correlation pattern in the first stage and avoid estimation problems in the second-stage multivariate model.
