nilearn.glm
: Generalized Linear Models¶
Analysing fMRI data using GLMs.
Classes:
|
The contrast class handles the estimation of statistical contrasts on a given model: student (t) or Fisher (F). |
|
Results from an F contrast of coefficients in a parametric model. |
|
Results from a t contrast of coefficients in a parametric model. |
|
A regression model with an AR(p) covariance structure. |
|
A simple ordinary least squares model. |
|
Class to contain results from likelihood models. |
|
Summarize the fit of a linear regression model. |
|
Contain only information of the model fit necessary for contrast computation. |
Functions:
|
Compute the specified contrast given an estimated glm. |
|
Compute the fixed effects, given images of effects and variance. |
|
Convert a string describing a contrast to a contrast vector. |
|
Return the Benjamini-Hochberg FDR threshold for the input z_vals. |
|
Report the proportion of active voxels for all clusters defined by the input threshold. |
|
Compute the required threshold level and return the thresholded map. |
