Yes Details below	No	Bug Reports Includes fixes

New features and changes introduced in this version are:

• Stochastic Algorithm Functionality in NLME Models

• k-Nearest Neighbor Searching

• Confidence Intervals Option in perfcurve

• Observation Weights Options in Resampling Functions

Stochastic Algorithm Functionality in NLME Models

New stochastic algorithm for fitting NLME models is more robust with respect to starting values, enables parameter transformations, and relaxes assumption of constant error variance. See nlmefitsa.

k-Nearest Neighbor Searching

New functions for k-Nearest Neighbor (kNN) search efficiently to find the closest points to any query point. For information, see k-Nearest Neighbor Search and Radius Search.

Confidence Intervals Option in perfcurve

A new option in the perfcurve function computes confidence intervals for classifier performance curves.

Observation Weights Options in Resampling Functions

New options to weight resampling probabilities broaden the range of models supported by bootstrp, bootci, and perfcurve functions.
