Most of regression analysis is based on least-squares estimates of the parameters of the linear regression equation. Although we have discussed some of the properties of the least-squares regression coefficient
Regression analysisEstimatorsHazardsRates (Per time)Stochastic processesWork which shows how a firm mathematical basis can be given to Cox's model is discussed. The original hazard rate definition of the model of Cox can be directly interpreted as specifying the stochastic intensity of a multivariate...
The last assumption of the linear regression analysis ishomoscedasticity. The scatter plot is good way to check whether the data are homoscedastic (meaning the residuals are equal across the regression line). The following scatter plots show examples of data that are not homoscedastic (i.e., hete...
In the group of participants with SCZ, the regression analysis showed an effect of disorganized/concrete (DIS) symptoms on sensitivity: patients with higher DIS symptoms rated using the PANSS showed a lower sensitivity for irony (b = −0.49, SE = 0.16, p < 0.01). Severity of...

As we have seen, regularization has to be performed when we have problems with the overfitting of our model. With respect to the Linear Regression model, we have better use Lasso regularization when we have a lot of features, since it performs even features selection; if we have highly corre...
The multinomial models contrast with results of models assuming unidirectional effects, where an association of current unemployment with adiposity was not supported by a linear regression of BMI (coefficient: − 0.30, CI: − 0.90–0.31), nor by a logistic model of obesity (OR: 1.15, CI: ...
regression analysis of the agents’ locations from neural activations (Fig.4d). In the early stages of learning, the agents’ locations could not be accurately predicted from the neural activities of either process-1 or process-2, but as learning progressed, the locations of agent-1 and agent...
This paper presents a D-vine copula marginal regression model for count time series data. Incident counts are expressed as a function of predictors. A time-varying discrete marginal distribution is used to describe the uncertainty of incident occurrences at an arbitrary time point, while the ...
