+# Mode
+
+> [Wald][wald-distribution] distribution [mode][mode].
+
+
+
+
+
+The [mode][mode] for a [Wald][wald-distribution] random variable with mean `μ` and shape parameter `λ > 0` is
+
+
+
+```math
+\mathop{\mathrm{mode}}\left( X \right) = \mu \cdot \frac{\sqrt{4\lambda^2 + 9\mu^2} - 3\mu}{2\lambda}
+```
+
+
+
+
+
+where `μ > 0` is the mean and `λ > 0` is the shape parameter.
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var mode = require( '@stdlib/stats/base/dists/wald/mode' );
+```
+
+#### mode( mu, lambda )
+
+Returns the [mode][mode] for a [Wald][wald-distribution] distribution with parameters `mu` (mean) and `lambda` (shape parameter).
+
+```javascript
+var y = mode( 2.0, 1.0 );
+// returns ~0.325
+
+y = mode( 5.0, 2.0 );
+// returns ~0.655
+
+y = mode( 1.0, 1.0 );
+// returns ~0.303
+```
+
+If provided `NaN` as any argument, the function returns `NaN`.
+
+```javascript
+var y = mode( NaN, 1.0 );
+// returns NaN
+
+y = mode( 1.0, NaN );
+// returns NaN
+```
+
+If provided `mu <= 0` or `lambda <= 0`, the function returns `NaN`.
+
+```javascript
+var y = mode( 0.0, 1.0 );
+// returns NaN
+
+y = mode( -1.0, 1.0 );
+// returns NaN
+
+y = mode( 1.0, 0.0 );
+// returns NaN
+
+y = mode( 1.0, -1.0 );
+// returns NaN
+```
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var uniform = require( '@stdlib/random/array/uniform' );
+var logEachMap = require( '@stdlib/console/log-each-map' );
+var EPS = require( '@stdlib/constants/float64/eps' );
+var mode = require( '@stdlib/stats/base/dists/wald/mode' );
+
+var opts = {
+ 'dtype': 'float64'
+};
+var mu = uniform( 10, EPS, 10.0, opts );
+var lambda = uniform( 10, EPS, 20.0, opts );
+
+logEachMap( 'µ: %0.4f, λ: %0.4f, mode(X;µ,λ): %0.4f', mu, lambda, mode );
+```

+## C APIs
+
+
+
+
+
+
+
+
+
+
+
+### Usage
+
+```c
+#include "stdlib/stats/base/dists/wald/mode.h"
+```
+
+#### stdlib_base_dists_wald_mode( mu, lambda )
+
+Returns the mode for a Wald distribution with mean `mu` and shape parameter `lambda`.
+
+```c
+double out = stdlib_base_dists_wald_mode( 2.0, 1.0 );
+// returns ~0.325
+```
+
+The function accepts the following arguments:
+
+- **mu**: `[in] double` mean.
+- **lambda**: `[in] double` shape parameter.
+
+```c
+double stdlib_base_dists_wald_mode( const double mu, const double lambda );
+```
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+### Examples
+
+```c
+#include "stdlib/stats/base/dists/wald/mode.h"
+#include "stdlib/constants/float64/eps.h"
+#include
+#include
+
+static double random_uniform( const double min, const double max ) {
+ double v = (double)rand() / ( (double)RAND_MAX + 1.0 );
+ return min + ( v*(max-min) );
+}
+
+int main( void ) {
+ double lambda;
+ double mu;
+ double y;
+ int i;
+
+ for ( i = 0; i < 10; i++ ) {
+ mu = random_uniform( STDLIB_CONSTANT_FLOAT64_EPS, 10.0 );
+ lambda = random_uniform( STDLIB_CONSTANT_FLOAT64_EPS, 10.0 );
+ y = stdlib_base_dists_wald_mode( mu, lambda );
+ printf("µ: %.4f, λ: %.4f, mode(X;µ,λ): %.4f\n", mu, lambda, y);
+ }
+}
