I think if you tightened up the convergence limits, fminsearch would eventually produce the same answers as mnrfit, but I didn't push that too far. I'd avoid conditionally evaluating log(P). If you wind up with P=0 (or worse, P<0), you want fminsearch to get a bad result so it can back away and try something else.
Mar 19, 2019 · All dichotomized analyses were performed with logistic regression using PLINK software version 1.90b4.6. 11 The full mRS was analyzed with ordinal logistic regression under a cumulative logit model using the MATLAB mnrfit algorithm (MATLAB Statistics and Machine Learning Toolbox Release 2016b; The MathWorks, Inc., Natick, MA). Under the ...

Oct 30, 2017 · Framing tasks were analyzed with logistic regression models. We first tested the four framing questions individually (using the function mnrfit in MATLAB corresponding to the function glm in R with a binomial logit link function) and then all four combined in a hierarchical model (using the function lmer in R). Specifically, we compared a model that only included the between-participants factors frame (gain versus loss) with a model that included the factor frame and the between-participants ...

I'm using MATLAB's mnrfit to perform multivariate binomial logistic regression. My inputs are an n x p matrix, X, with observations as rows and predictors as columns (there are no missed observations/NaNs), and an n x 1 column vector of labels, Y, indicating the class as either "1" or "2."

Jun 17, 2011 · At each iteration, observations are added to the mnrfit predictor matrix (X). Curiously, the convergence failure only happens after several iterations in which mnrfit converges successfully, meaning that the non-converging runs actually have more observations than the converging ones.
Repmat in Matlab is one of the commands in Matlab which is used for array manipulations. This command gives output in the form of an array repetition of the original array.

The default is a model with different intercept and slopes (coefficients) among categories, in which case mnrfit fits a sequence of conditional binomial models. The 'interactions','on' name-value pair specifies this in mnrfit. The default link function is logit and the 'link','logit' name-value pair specifies this model in mnrfit.

The 'link','logit' name-value pair specifies this in mnrfit. Log cumulative odds is the logarithm of the ratio of the probability that a response belongs to a category with a value less than or equal to category j , P( y ≤ c j ), and the probability that a response belongs to a category with a value greater than category j , P( y > c j ).
