The cubic Hyperbolic B-spline has produced much better errors than the Quartic Hyperbolic B-spline. The statistical validation of the parameters is also provided via generating the correlation matrix heatmap.doi:10.1007/s10910-024-01652-2Mamta Kapoorhttps://ror.org/00et6q107grid.449005.c0000 0004 1756 737XDepartment of Math...

Hello, I am fitting a spline -- or a piecewise model as it is referred to in the Mplus manual. I have four time points and two groups. Is there anything obviously wrong with the following code: i s1 |YEAR1@1YEAR2@2YEAR3@2YEAR4@2; i s2 |YEAR1@0YEAR2@0YEAR3@1YEAR4@2; i ...
