Can you hlep me understand this graph and what it means?

Ca$11$:

lars $1x=x,y=$ prostate$lcavol, trace $=$ ThUE$)$

R$-$squared: $0,$$$64$

Sequence of LASSO moves:

$1$ pta lep age gleason lbph

The eraph of the L$.$ASSO estimates as a function of the shrinkage illutates

the ender in which variables enter the model as one relaxes the constraint on the

LI norm of their estimates. Initially there is aothing in the model $($look to the

Ieft of the graph, where $x=0.$ Moving to the right on this graph, one finds that

the first variable to eater is variable $5($Ipsa$)$; then variable $3($lep$)$ eaters; then

variable I $($age$),$ Or$,$ scanning the graph from the right$-$hand side to the left. we

notice that variables $2($Ibph$),4($gleason$),$ and I $($age$)$ are "zeroed out" in that

order. Below, we list the parameter estimates for selected values of shrinkage:

$s=0\mathrm{.}25,0\mathrm{.}50,0\mathrm{.}75,$ and $1\mathrm{.}00.$ The LASSO estimates for $s=1$ are the ordinary

least squares estimates $($see the prior regression output$).$
