how do you find a log-likelihood what is a log likelihood weighted sum of squared error is calculated how to use t distribution and autocorrelation in regression how to get statistics with normally distributed errors which regression type assumes normally distributed errors what is the objective function in regression what is the t distribution used in regression how to compute the log likelihood how to do regression for t autocorrelated errors how should standard deviation be weighted in regression? if i assume normally distributed errors how do i compute the log likelihood what is the statistical model for autocorrelation how does a statistical model work what is the objective function in a nonlinear regression which of the following is the statistical model in nonlinear regression with t distributed autocorrelated errors? does regression model include t based errors? what is the statistical equation for the weighted sigma does the objective model include t distributions how to do the logistic regression with t distributed error
