New Features

64-bit option

With the 32-bit version of NCSS, analysis of datasets with greater than 25 million cells can result in memory errors. The 64-bit version of NCSS 10 increases this limit by many, many times, so that the analysis limits are only those imposed by the amount of memory on the computer. The purchase of NCSS 10 gives you access to both the 32-bit and 64-bit versions.

Enhanced Data Stacking and Unstacking Tools

NCSS 10 includes improved tools for stacking and unstacking data. New options in the stack data tool allow you to automatically rename output columns and include label columns in the stacking process so that information about each observation is maintained in the stacked data. The new data unstacking tool also allows you to include label variables and automatically renames output columns. It also allows you to unstack data using a grouping column, which provides greater flexibility in data processing.

New Contrast Variable Tool

NCSS 10 includes an all-new data tool to help you create a set of contrasts or binary indicator variables from categorical data columns. These new variables are stored right on the data table.

New Transformations

NCSS 10 includes new date-variable processing transformations that allow you to work directly with Date-Time values without having to first translate them to Julian dates before extracting Month, Day, Year, etc. from the date values. NCSS 10 also includes a new transformation to convert Julian dates to Date-Time values and Date-Time values to Julian dates.

Copy with Filter

NCSS 10 includes a new data copy function that only copies values from rows that pass the filter.

Features and Procedures added in the NCSS 9 Upgrade from NCSS 8

A major focus in the upgrade from NCSS 8 to NCSS 9 was the improved interface and output for many of the commonly used procedures. Several useful new procedures were also added.

"I purchased NCSS last week and have been extremely impressed with the product so far. The documentation is superb... Especially strong is the importing of files from Excel and other statistics programs..."

Gary Brager, Baltimore County Public Schools

"PASS is a great program. It does so much and is easy to use. It’s much better than the other sample size programs I’ve used—it has helped me greatly in my research."
